Feature Request: Favorites

Hi Cryptomator-Team,

first of all: Many thanks for this great product!

I’m using it with my Mac and iOS devices.

It would be great to have a “favorites” functionality in the iOS App, similar to the favorites functionality Dropbox offers.
Especially if you are using deep directory hierarchies it’s very handy to define favorites e.g. per Vault to jump immediately into the most used directories without the need to navigate through the whole directory hierarchy path.
