Hide individual libraries
In a relational database, some tables serve as static data repositories. These tables should be isolated from the front-end users. In Memento it is currently not possible to "hide" libraries (i.e. tables) from the user. This means static tables cannot be implemented as users can always see them and potentially alter them.
A simple option to hide library tiles in a group would help admins to set up Memento on devices in such way that static tables could be used to serve content to libraries (e.g. to use a relationship instead of the single choice lists).
