Feature/Enhancement Request | Expandable Tree View in Rootless mode

[JosephLai241]

Provide Context for the New Feature or Enhancement You Would Like

There is currently no way to scroll or expand the Tree (Normal) View within Rootless mode. This may become an issue with longer filenames, deeply nested items, or when displaying file metadata.

I would like to add two different ways to adjust the size of the Tree View:

• Add a keybinding that will expand the Tree View so that it takes up the entire width of the terminal, hiding the File View in the process.
• Add two keybindings to increase or decrease the width of the Tree View incrementally.

Explain Why You Believe This Would Be a Good Feature

It would be nice to see everything in the tree.

Ideas for the new keybindings:

• Map "F" for the Tree View to toggle fullscreen/full-width mode.
• Map "+" and "-" for the Tree View to increment/decrement the width of the widget.
