Firstly, thanks Hackaday editors for featuring this project on the homepage and thanks hackaday.io users for making it trending (for a short while, but i'm grateful)!

So, I finished the input of characters not on your keyboard. I have coded both GTK-methods see HERE.

When uni stats again in march I will add windows (alt-numpad) too, but until then i don't have access to a windows machine.

I also restructured the code in `main.c` a little bit (keyboard layout selection is now a function on its own, as it is used in two places) and added some error codes.
