Use better on-screen keyboard

[SomeoneToIgnore]

Landscape mode, current rootfs keyboard:

Landscape mode, Android keyboard (top overlay with ESC, arrows and other symbols comes from termux, not the keyboard per se):

Current Gnome on-screen keyboard is very hard to use:

• it's relatively slow to draw on e-ink (esp. the pressing animations) due to being very dark
• there's plenty of ghosting on the keys
• the distance between keys is very small, same as the keys themselves
• the digits/special characters are relatively inconvenient to turn off: ?.. button is not on the edge of the keyboard as on almost every modern mobile keyboard
• the digits/special characters are very inconvenient to input: the keyboard toggles back to letters after every digit/symbol input, so the default 1234 user password has to use 8 symbols that are relatively slow due to redrawing dark animations being slow

I agree, the keyboard is sometimes really unusable. However, I'm still not really sure what to do about it. I also think there are at least two onscreen-keyboard variants in gnome, with the new one being caribou, https://gitlab.gnome.org/GNOME/caribou. It says there "configurable", but I do not understand how to actually change anything at runtime...

There exists an extension to improve the osk, but a rewrite for gnome 43 is still in progress, see: https://github.com/nick-shmyrev/improved-osk-gnome-ext/issues/30

Still, there apparently is a wip branch working on gnome 43
