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 tried learning GTK once... once.

@bryanredeagle

Heh, I got the book on it circa 2001.

I got as far as "Here's how we fake OOP in plain C...." 🤣
