[Feature Request] "Expand recursively" function in Browse window

When browsing through folders that contain a lot of other folders with single files in them in Browse window, it would be very helpful to have "Expand Recursively" function available when working with folder listings.
As a context menu option on a folder with a mouse Right click, or as some other shortcut option if we don't want to clutter the "right click" menu (like "Alt+Left mouse click" on a folder to expand it recursively, or "Alt+Right arrow" while selection is on the folder to expand it recursively).
