Keyboard layout optimized for polish
It's based on engram layout, but at the moment differs a lot. Polish characters arranged almost all on home row.
For Linux and Windows. On Linux just change /usr/share/X11/xkb/pl. To install on Windows you need to download MSKLC first, load .klc file -> project -> build DLL and setup package. Then simply install .exe from build directory.
now this layout is OP for polish, and good for english too ;)
I also highly recommend to try ctrl-capslock swap and sticky buttons - it significaly improves ergonomics
