 ## TODO
 - use libuv functions instead of `touch` and `mkdir` in `create_file()` and allow file creation with path like `foo/bar/baz`
-- better vim help docs
 - cd command to move faster accross the fs if needed
 - quickly find file in the directory structure
 - tree should always stay on the side no matter what
 - add global ignore parameter
