Tired: Forking #GIMP because the name is bad.
Wired: Forking GIMP to keep it GTK2, or somehow (lol) switch it over to a sane UI toolkit, like Qt... or WxWindows... or Tk... or XForms... or QuickBasic... or a flipping Abacus.

Any takers? 🤣

Addendum:
Inspired: Saying 'Eff this' and just using KolourPaint... or a pen and a napkin 😂

@rl_dane I have genuinely been tempted to write a full software suite in TCL-TK, including media players, converters, and editors
@rl_dane The really hard part is, I'm a total idiot when it comes to things like video codecs, so this software suite is gonna have a lot of dependencies, and I _hate_ dependencies :P

@OpenComputeDesign

Here's some inspiration:

Go here and run this emulator in yon web browser:

https://infinitemac.org/1984/System%201.0

Click on the little apple menu on the top left, then try each and every option under that.

And write one tool each to replicate all of those options (the about box and the 8 "Desk Accessories").

Well, don't try to replicate Monkey, that's just a test program to try to make the OS crash.

A classic Mac loaded with everything you'd want.
