Allow multiple documents to be selected at once and updates common values in the custom form, or do other actions besides the currently existing (delete, share, move, download)
I would add to this the ability to select and email out multiple docs to a user. The share function today just gives them access to view. The use case is you want a Product Manager to review a guide and a flyer created for their project, you'd like to send both to them for review. I would also add the ability to select multiple documents with the ability to assign an approver to review/approve both documents.
