It has been another productive month working on GNOME Design and Community Management as part of my Sovereign Tech Fellowship, and I want to share some of the most interesting developments.
Introduction
I want to begin by highlighting how much the Sovereign Tech Fellowship has changed the conditions under which I contribute to GNOME. As a volunteer, I had to fit my contributions around my day job, working on GNOME in the evenings and during holidays. The Fellowship has enabled me to significantly expand the scope of my work. I can focus more on platform-level design and work on structural changes that make it easier for others to contribute. This type of work reaches many people, and it makes me feel particularly effective.
At the same time, working on GNOME is now my job, which allows me to maintain a much clearer separation between work and free time. I am really enjoying having more time for sports, and I have also started taking regular piano lessons again. I spent the last two weeks of August on holiday in nature and returned feeling refreshed and motivated.
Thank you very much to the Sovereign Tech Agency for this opportunity!
GNOME Circle
GNOME Circle is a certification for high-quality third-party apps that also serves as an educational program for app developers and designers. Unfortunately, GNOME Circle had to close applications in May because the small team of volunteer reviewers could not keep up with the large backlog of unreviewed apps.
Thankfully, several people responded to the call for reviewers, and Tobias recently introduced Sjoerd, Will, FineFindus and me to the review process. Sjoerd was able to start his first reviews of Concessio and Iconic immediately, drawing on the design experience he gained from receiving the Circle review of his app, Graphs. I also started reviewing two apps: Quadrapassel, a Tetris clone, and Mecalin, a keyboard typing lesson app. Quadrapassel is developed by Will, and my review aims to share some of my design experience before he starts reviewing submissions himself. FineFindus has started reviewing Field Monitor, and Tobias and I provided feedback on their review before it was posted publicly.
This represents a significant increase in our review capacity, and I am optimistic that we will soon complete the remaining reviews and then be able to reopen submissions. I would like to thank all previous and current Circle Committee members for setting up and contributing to this program, as well as for reviewing all the excellent GNOME Circle apps. If you want to get involved, reach out on the GNOME Circle Matrix channel.
Scale Row Standardization
Libadwaita provides several types of boxed-list rows for common use cases, such as text entries, password entries, switches, and dropdowns. However, it has so far been missing a row with a scale, which has led apps to implement custom widgets with inconsistent styling. Let’s change that.
I started the Scale Row design process by collecting screenshots of existing use cases and examples of state-of-the-art designs from other platforms. Looking at other platforms is always helpful, but I also needed to take into account the requirements of our design system and its technical capabilities. Because Scale Row will be based on Action Row, it needs to support a title, subtitle, prefix widgets, and suffix widgets. To make the layout work in narrow windows, it also became clear that the scale should be placed below the title. Several rounds of sketching, mockups, and discussion led to the following preliminary design.
Originally, I intended to design only the row layout and use the scale as it was. However, aligning the start and end of the scale with the labels and icons required us to change the scale’s padding. That change has already landed in Libadwaita, and we decided to take the opportunity to review the scale’s style as well.
I found that the current style does not follow our design system’s 6-pixel grid, and that the knob is smaller than the minimum target size required by the WCAG accessibility guidelines. I therefore proposed several options inspired by other design systems. What we can adjust is largely restricted by what GtkScale technically supports, and I believe we may settle on the proposed pill-shaped style. The pill-shaped knob satisfies the WCAG requirements because a 24-pixel-diameter circle overlaid at the center of its bounding box does not intersect with adjacent targets, such as the scale’s trough. At the same time, the pill-shaped knob does not increase the scale’s height and therefore does not introduce additional whitespace into Scale Row.
While reviewing the scale style, I noticed that an issue filed in 2024 regarding the scale not aligning with the direction of swipes on touchpads had been resolved. Thanks to Carlos, the physical direction of touchpad gestures is now correctly forwarded in GTK, and GtkRange and GtkScale already follow it. This also means that other Libadwaita widgets with semantic motion, such as NavigationView, SplitView, and Carousel, can finally follow the physical swipe direction on touchpads, regardless of whether the user has selected natural or traditional scrolling in the system settings. Alice has already opened a merge request for this change. Ideally, this change should be coordinated with the shell so that gestures such as the three-finger swipe for switching workspaces or opening the overview also follow the physical swipe direction. We also discovered a bug that causes the knob to appear off-center. The bug has technically always been present, but it was less noticeable with the circular knob.
Technically, Scale Row will be based on Action Row. Alice therefore proposed implementing a generic bottom child that also supports other use cases involving widgets below a row header. I included examples such as toggle groups in narrow layouts and a participant list in a calendar event in the mockups to account for their requirements.
A New Era for Calendar(s)
Calendar is where I started contributing to GNOME, and I have spent a lot of time designing for it over the past years. The Fellowship enables me to expand my responsibilities to other apps and shift my focus towards platform-level topics. Nevertheless, designing for Calendar will remain important. From a design perspective, it is one of the most complex GNOME apps and uses many patterns that other apps need as well. This makes it an ideal place to develop design patterns and technical solutions that benefit the entire platform.
At the beginning of September, I finalized a new version of the mockup for Calendar’s top-level app structure, based on discussions I had at GUADEC. Since 2024, we have been discussing Calendar’s top-level structure to define a roadmap for developing a fully adaptive app that works equally well on mobile and desktop. This involves several significant changes, and we have not quite reached that goal yet.
I am therefore especially excited to see multiple contributors implementing parts of the design this month. Hari implemented the new layout, Markus resumed work on his merge requests for touchscreen support and the mobile month view, and Zelda is working on the adaptive event details dialog that will replace the event details popover on mobile. Thank you all!
Recently, the first beta version of Era was released after more than a year of development. Era is a third-party calendar app developed by Titouan in close collaboration with me. You can download Era from Flathub and please report any bugs you find.
Initially, I had some concerns about duplicated development efforts, especially because GNOME Calendar is currently a thriving project with many active and skilled contributors. However, the two projects differ in several important ways that justify developing them in parallel. So far, I believe they have benefited from each other.
One of the main differences is that Era already implements my latest designs including year, month, and agenda views adapted for mobile. These views are used for navigation themselves, rather than relying on separate navigation controls. On desktop you can use the small window side-by-side with other apps for multitasking or go fullscreen for complex planning.
Under the hood, Era is written in Rust and uses Clepsydre, an extensible and modular calendar backend. It currently integrates with Evolution Data Server, while an experimental peer-to-peer backend based on p2panda is also available in development builds. Work towards Android support is underway, and an APK is available through the CI pipeline.
