for managing contracts (collections of documents) I'm using a Document Library per contract. I will end up with hundreds (500+) of document libraries.
Is it possible to make custom views on the list of Document Libraries in a site? As far as I can see, they are listed as "boxes" (in the Site Contents page).
Can I let the user filter the document libraries by name or other properties?
Can I attach custom properties to a Document Library itself? (eg. the external ID of the contract, the customer name) Or are they to be attached to the content as columns?
