Customizable keybindings

[yelircaasi]

This app is amazing and I already love it. The one thing missing that would make it absolutely perfect for me is the option to have vim keybindings. These could be implemented as a separate layer that can be switched to in the settings or (my preferred approach) by making each shortcut customizable.

This is something that would really make this app appeal to power users, especially since most of the other good GUI file browsers (Thunar, PCManFM, Nemo, Dolphin) are specific to one desktop environment and pull in a huge set of dependencies, whereas this one is nicely self-contained and uses a modern stack.

Let me know if this is something you consider worth having. If so, I'd be happy to work on it and make a pull request. Thanks again for this amazing project.
