Given that the repo seems to be abandoned but is the only usable one (comparing to https://github.com/bernardo-bruning/godot-vim), should we use your fork as a base to include other open PRs and move forward @binury ?

Nice PR! I would suggest to not to commit the white space changes in your commit. It may down to personal preference but it's good to respect the original tab/space convention unless it's a dedicated space re-formatting PR.

On another note, similar to this change, any chance anyone has figured out how to do sequential key mapping?

For instance in other VIM editors I mapped typing f then d within one second to Escape to exit insert mode
