Thumb key started with a pretty small amount of layouts. While creating a variant and PRing it might not be the cleanest solution, it definitely works. There have even been rejected open PRs adding in-app layout customizaiton (to some degree), and they were rejected mainly due to unnecessary complexity.
Here are my few main reasons I think the current system is fine:
One of the only major downsides is that a new user might have a harder time finding the appropriate keyboard layout. However, if somebody is installing thumb-key, there’s a 99% chance they’re either a former MessagEase user (in which case they just select the MessagEase layout and continue with their life) or a curious person who is willing to experiment with a weird keyboard like this and try out 4 or 5 different layouts they find interesting. There are some ongoing discussions in the issues about a better naming scheme for the layouts, so new users can distinguish them better.
Implementing a in-app layout modification system with good UX would be very time consuming, and the developer’s main project is working on lemmy and the Jerboa app - I imagine there isn’t really that much time left to sink in hours for such a big feature. Most, if not all “bigger” features like slide gestures were several PRs from several differennt people, sometimes over the span of months.
Creating and maintaining your layout isn’t that hard - it can even be done without android studio, and in 1-3-ish iterations over the course of a week or two you get a layout that you are likely to use for a long time (at least, that’s how it was for me). Dessalines is, in my opinion, exceptionally quick in merging PRs and making new releases, so it’s really not that bad.
