Making a new keyboard layout

[dukla2000]

This is almost a showstopper - the choice of keyboard layouts is very sparse in current Mobian, and I can't quite find a way to make a new one.
I read almost everything that was written here on the subject, and followed the instructions on https://developer.puri.sm/projects/squee...orial.html

The trouble is that (megi's) distro of Mobian, and a few other descendants of Debian, includes about eight keyboards for major languages, and then there's the „other“ section, where I found both of my serbian keyboards (cyrillic and latinic) listed. However, when I select one of these, nothing happens, the layout remains american. So I found that the layouts reside in .yaml files on

~/.local/share/squeekboard/keyboards

...which doesn't exist. So I made one, and edited my version of sr.yaml, put it there (using syncthing, which works miraculously). Still doesn't catch. Searching through files, I see there's some trace of squeekboard, but no recognizable keyboard files anywhere.

I'm at my wits end - was there anything changed in the mechanism? Perhaps current Mobian doesn't even use squeekboard anymore? Where are the layout files?

No idea where the "installed" keyboards go, but I have my own (gb.yaml) in
~/.local/share/squeekboard/keyboards/terminal/
and it selects & works just fine when I select the terminal option on the default keyboard.
