Browsable document's metadata list
The Android app could allow the user to access the document files by clicking an item in a browsable list of metadata (book title, author, year of pub, year of add, ...)
Metadata includes information about the document and its contents, such as the author’s name, keywords and other information.
It would be very nice if it would be possible to view the metadata of all files located in the database! It will be easy to sort, search for the desired document in a huge database!
