Thanks for this.
I just tested it, no errors here so far, seems to work fine.
I like such "creativity aids" when the damn writer's block is round the corner.
Though I hope the Reaper devs can somehow make working with tkinter apps like this a little less quirky.
Currently:
- hides behind Reaper's window when clicking anywhere in Reaper
- no undo (as said, but probably hard to implement)
- steals Reaper's keyboard shortcuts when in focus
