The Coppice Private Beta


For the best part of a year we have been at hard at work on Coppice, designing interfaces, building features, and fixing bugs. Over that time only a small handful of people have been able to try out Coppice and offer feedback on it. Now, we're happy to announce we're looking to expand that group with the Coppice Private Beta.

We're looking for people who would like to help us shape the initial release of Coppice and iron out any bugs we have missed. You can register your interest in the beta at the Coppice Private Beta page. Just enter your name and email you will be added to the waiting list. We will start selecting people to join the Coppice Beta soon.

Please note that Coppice requires a Mac running macOS 10.15 or higher, so make sure your machine can handle that before signing up.

We can't wait to get Coppice into the hands of more people and see what you think.

Designing for macOS Big Sur


Coppice has been under development for close to a year and its interface has undergone many design changes over that time. We had finally got the interface into a state we were happy with a few months ago and were expecting to ship with that interface this Autumn. Then along came Apple with WWDC…

Every developer goes into WWDC week expecting that they'll have to make some changes to their apps. There are the inevitable bugs that new OS versions introduce, and the new platform features to implement. And then, every so often, Apple decides to completely redesign the visual appearance of the OS.

The first thing to do when this happens is install the new beta OS and launch your app to get an idea of the damage. Thankfully, in Coppice's case, it wasn't too bad. As you can see in the screenshot below, most of the UI updated just fine.

The bulk of the work that needed to be done was with the sidebar and the toolbar. In simple cases, icons and controls were just misaligned. However, Big Sur is not just a visual update to sidebars and toolbars, but also updates how these work, and what counts as "standard" behaviour.

First, the sidebar. Big Sur makes a full height sidebar the new norm. This was thankfully a relatively easy thing to implement and makes a huge difference to fitting in with the new aesthetic. Besides a few bugs fixes not much else had to change.

Next, the toolbar, which represents the biggest change. Previously a window had a title bar, containing the window's "traffic light" buttons and the title of the window, and a toolbar full of controls below the title bar. In Big Sur these can both be merged into one.

The first change we made was to break up the sidebar/inspector toggles. Previously the convention was to have such controls grouped together, but Apple has moved them to the left and right sides of the toolbar in their apps with Big Sur.

Next, we looked at the New Page control. One of the changes to Big Sur is developers can link toolbar items to panes in a split view. In our case this allows us to move the New Page button to above the source list in Big Sur.

The bottom toolbar shows the new page item shifted above the sidebar, the toggle sidebar and inspector items split up and put either side of the, and new icons for all toolbar items

We also took this opportunity to rethink how the control works. Previously you could click on it and get a menu to select the page type. This is great if you're wanting to make pages of different types, and the final version of the control still works this way if you click and hold on it. However, it made creating many pages of the same type just that little bit harder. To fix this we made it so that simply clicking on the button will now create a page of the same type as the last page you created. It's an example of how having to redesign for a new OS can help improve things for users on older OSes too.

Finally, we have the icons. Apple has built up a large collection of icons for developers to use over the past few years called SF Symbols. These help to give a more consistent look and feel to the platform. With Big Sur, Apple has brought this collection of icons to the Mac.

We wanted to replace the icons in Coppice with these new icons. Unfortunately though, they don't work on macOS Catalina. To work around this we decided to re-create the icons ourselves, so we can keep them consistent across platforms. We also added some of our own, such as for the Canvases item in the sidebar.

This also had another benefit. Traditionally, icons like this have been designed to perfectly align with pixels on your screen. This helps keep them crisp, clear, and easy to understand. Unfortunately, Apple's new icons are designed to be infinitely scalable, which means they don't do this pixel alignment. This isn't too bad at large sizes, but at the sizes required for use in most apps it can lead to them looking very blurry, especially on non-retina displays. By re-creating the icons ourselves, we were able to fix this issue, so they should look crisp no matter what Mac you run on.

In case it is a bit hard to see the difference, here is the same image scaled up. Note that in both cases these images show non-retina versions of the icons.

Why Create Coppice?


Last week we took a look at Coppice's features and interface, looking at what Coppice is. This week we'd like to take a step back and talk about why Coppice exists. There's little point in creating a solution unless there is a problem to solve. So what problems is Coppice trying to solve, especially in a market that is replete with apps to let you take notes?

The Problems

There is a principle with programming that you should optimise your code for readability, as anyone working on that code will spend far more time reading it than writing it. This principle is not limited to just code though, it can apply to any sort of information.

There are plenty of apps out there that are excellent for collecting information, for taking notes, etc. They optimise for getting information into the app, but allowing you to actually use that information is often a secondary thought. They offer basic tools such as grouping, sorting, and searching. Some apps even use machine learning to help surface what they think might be relevant. However, they all assume that once you've found that piece of information, that's all you needed to do.

The second problem is these apps don't treat information as intrinsically interconnected. Again, you can do things like create links between bits of information, but these merely navigate between information. They don't treat the relationship as a first class citizen, nor really allow you to view all these connected bits of information at once. This promotes users to create fewer entries in the app, but make each entry bigger, such as having large sprawling notes that contain multiple thoughts or ideas.

The Solution

Coppice tries to solve these two specific problems. It is optimised for using information over collecting it, and it promotes using smaller but interconnected Pages rather than a few large sprawling notes. This is visible in many of the concepts and design choices in Coppice.

One of the first things you will find is that Coppice is a document-based app. It is not designed to be a central repository of all your knowledge, but series of documents focused on understanding particular things. This lets you keep unrelated things isolated, essentially letting you explicitly state that two bits of information don't have any relationship by having them in separate documents. After all, there's no reason why the information on that client project for work should be held in the same library as the information on redecorating your kitchen at home.

Next, Canvases let you visually organise these thoughts on your computer. We do this all the time in the real world, from laying out papers on a desk to drawing on a whiteboard. However, unlike the real world Coppice can give you an ever expanding space to grow your thoughts.

Canvases also allow you to see the relationships between bits of information. When you open a linked Page on a Canvas, there will be an arrow between the two Pages showing the relationship. This makes the relationship a concrete and visible part of understanding your thoughts. This can also help you see relationships you have yet to make. If you place two pages close to each other on a Canvas, but they don't have an arrow between them, maybe that's a sign to you that they should be linked.

These relationships can also depend on context. You may want the same collection of Pages to be grouped or linked differently in two different contexts. To solve this, Coppice Pro allows you to have as many Canvases as you like, giving you many different views on the information in a document


These high level concepts are all well and good, but what does this look like in practice? Here are a few examples from our own usage of Coppice:

Learning a new Subject

A key part of building and selling any piece of software is learning new things. One of the things we needed to learn was how to set up and handle payments with our payment processor. This required reading their documentation and creating notes. As this required learning about many topics, Coppice was perfect for the task.

We created a Canvas and added Pages as we moved through the payment processor's documentation. As we had multiple Pages on screen at once we were able to add the information we found to the appropriate Page, so that it fit the mental model we were building as we learned.

Running an RPG

At M Cubed Software we enjoy playing table-top RPGs. If you have ever run such a game, you may know that it requires keeping track of a lot of information: locations, characters, plot points, player backstories. It's an ever-changing, ever-growing story, and one that requires the ability to think quickly and improvise to what your players choose to do.

You can use Coppice to store all the information on the campaign you are running. You might create a Page to represent a town in your world, then create linked pages for all the locations in that town, which in turn link to pages on characters the players might find in that location.

You can then use a Canvas to organise information that you think may be relevant for the next session you play, but you can know that any related information will always just be a click away if you need it.

So that is some of the thought process behind why we built Coppice, and why Coppice works the way it does. What ways will you use Coppice? Let us know at @mcubedsw on Twitter.

Next week we'll be talking about how we re-designed parts of the Coppice UI for Apple's upcoming macOS release: Big Sur.
