Use your favorite keyboard layout everywhere! I learned the Colemak keyboard layout, but for example I can not install it at school, so I wrote a portable keyboard layout program using autohotkey. It doesn't require an install or administrator privileges.
Just copy one of the folders in Portable_Standalone and start the pkl.exe file.
There exists a fork with very active development at https://github.com/DreymaR/BigBagKbdTrixPKL Maybe you'll find some other options you would like there.
