Add feature to auto-collapse folders not in use upon closing a file

[ProLoser]

So I love this package, but after a while my tree gets kinda big and shows me folders I'm not using anymore. It would be nice if there was an option that when you close a file, if no other files in that folder are open, it should collapse the folder in the tree view, and so on, recursively until it hits a sibling folder/file in use.

@ProLoser sounds like a good feature to have.

Also you should add the option to NOT call 'reveal' when you just change tabs vs opening a new file

I mentioned in the sublime synced-sidebar , there seems to be no corresponding api. Do not know if the atom can achieve this function.
