This looks really slick! I wish I could remember where I stumbled across this project - either Twitter or Reddit.
I have a Linux laptop and it seems to work well there, except it shows the wrong time on the initial screen. It's showing "Tuesday, December 2021" as the date. The time appears to be correct but 24 hour clock - it would be nice to have the option for 12 hour clock.
I see you've also talked about MAYBE have a Mac version. I'd love to try it out and give feedback whenever it's available.
Last but not least, I've got a couple ideas for apps and had thought I could either spend what little time I've got for side projects on games OR apps. Now I see I may be able to build the apps I want in Godot to learn the engine and maybe later work on games. Thanks for the inspiration!
