Feature Request: ability to change the order of the menu-items of the SPPB Media Manager by hand and to hide menu-items (or role-defined rights)

The Media menu of the SPPB Media Manager opens with either with the "All items"-option or with the "Images"-item by default. Please add these options to the SPPB Media Manager:

1. ability to change the order of the menu-items by hand, so I can have the "Browse folders"-option on top and order each folder position myself.
2. ability to hide some of the menu-items, so I can force users to only use the "Browse folders"-option

Reason: With the other menu-items options the storage of media tends to become very messy, and I don't want that.
