I'm really loving this tool and it has helped me improve on both personal and work projects! Tried it, buyed it, zero regrets. On Windows 10 x64 the experience is flawless. On linux x64... not so much. Dragging the window around is very sluggish and jittery. Resizing the window is impossible. It just stops rendering altogether. No timers are going, fresh setup, no notes, nothing. Godot itself isn't quite as snappy as other applications, but it's light years better. Actually clicking through the interface is fine, but trying to wrangle the whole application window is an ordeal. This is perhaps minor as I work, unfortunately, in Windows and that's where I need it most.
One feature that I feel is sorely lacking is the ability to create multiple custom timers. The stopwatch and Pomodoro timers are perfect and do what I need. However sometimes I want a 30 minute timer, sometimes 10, sometimes 60. Having to constantly modify the Pomo settings is pain.
Lastly, and real moonshot here, it would be nice to do some basic reporting on project progress, task start and complete dates, with time spent total and per task maybe in a kind of heatmap or something. I'd totally be open to contributing in this area. I do data analysis on enterprise storage and I'm preparing reports for customers almost on a daily basis. This is my jam.
