Ability to add custom vim binding, possibly reading from vimrc

Is your feature request related to a problem? Please describe.
Some of us have custom vim keybindings, to which we are used. I and many others don't use the standard hjkl cursors, but have them mapped on jkl; (personally I have them on jklč, because I have a slovenian keyboard). Intellij reads vim mappings directly from vimrc, sublime and zsh have the possibility to customize them. I miss something like that in insomnia.


Describe the solution you'd like
An .init file with to customize settings, like, in this case,
[noremap č l
noremap l k
noremap k j
noremap j h]
