Dumb Ideas Done Dirt Cheap : 👆 this but for linux; my GPD Pocket 3 has a really nice wacom display with active pen, let's use it to write some hecken text!!!
myKbd and ATOMIK
myKbd by Alex Pruss was a little hexagonal input method designed for pen/stylus interface, with the placement of keys based (iirc) on some text-analytical research published in the early naughts by IBM called ATOMIK.
if you started or ended on the center tile it would insert a space, but if you dragged the stylus through it on the way to other letters to construct words it would be a nop. this allows you to drag things like stop for example on the keyboard at the top of the doc in one fluid swirl, a critical skill to speedrun in these times.
You were able to access all the symbols, the OS-wide shortcut gestures are keys on the keyboard, it worked very nice back then.
linux virtual input methods
i tried reading the maalit code and found it to be too abstracted and dense to really work with. there's squeekboard too
i don't know the first thing about writing an IME but i oughta figure it out!
I solicited information here on Mastadan . didn't get much back
