Control default level of depth to collapse / expand menu on left#36

When you have a lot of docs in the wiki, the menu becomes a bit of an overload because it seems to expand from top to the lowest level folders in Google Drive and shows all individual docs.

See image attached.

It would be nice if we could say something like “expand up to N levels deep” by default.

Other nices to have:

• Give users ability to click to expand / collapse, and remember there last clicks. Also give a “collapse all” option?
• Allow owners/admins to set a default depth that varies by folder. E.g. maybe the top-level “Sales” folder has certain directories expanded down to 3 levels, some down to 2, and the top-level “Product” folder is - for example - not expanded at all.
