Feature request: setting few keymaps for multilingual use

[kukushkawi]

I'm opening this issue because:

• I'll report a bug
• [+] I'll propose a new feature

Description

Option to write additional keymap to use alongside with standard. My main language is ukrainian and I use it very often, even though I'm still using english keyboard layout because of this extenstion. It will be very useful for users who know a bunch of languages.
