[Concept] Right Zone browser

hello!
I found right zone browser very useful except one thing, file browser. you can’t use your arrow keys to navigate and listen samples, it slow down your workprogress.

i propose make some tweaks with keyboard:
Backspace - go back (like explorer in windows)
Enter - open selected folder (like explorer in windows)
Left arrow - back to top inside folder
Right arrow - play selected sample
UP/Down - up n down

Also, folder tree inside TAG section, maybe switch button Tag’s/Folders
