[BP Group Documents] Adding 2 options

A client of mine is working with lots of volunteers for different activities. They are connected through groups in BuddyPress. For some groups confidential documents need to be shared. For that purpose I have installed the plugin BP Group Documents. It suits its purpose. Yet, I am looking for 2 additions to this plugin:

– a search function, searching on the document name, display name, and description text. The search should be limited to the documents in that group.

– a print function, printing the used selection criteria, and listing the (selected) documents, the display names and the description text.

Could you help here?

Thanks so much.
