File tree pane folding utitities

It seems not easy to navigate files in large git projects when there are a lots of folders (possibly nested), we can only use arrow keys to navigate? Currently, I know we can use `-/+` to collapse or expand all file tree, and use `/` to search files. IMHO, it would be better if lazygit can support use shortcuts to fold the file tree in different levels, e.g., in `tree` command we can use `-L` to specify the levels or as in some editors, we can fold codes in different levels using shortcuts. Hope I made my suggestion clear.
