Improve bulk deleting of media in Guide

Feedback for improvement on the bulk deleting of media feature:

• The new feature is good, but it would be better if the system can identify which media are not used in help articles. It is a bit tedious to click the media one by one to figure out the media is being used or not.
• In addition to Your media, all media, it would be nice to have additional menu that stores all the media that are not being used in any of the articles (possibly, 2 menu for your media and all media so that can specify).
• It would be nice to have a filter who upload and can search based on the uploader.
• It would be nice to delete more than 30 media at once (maybe 100 at once similar to Zendesk Support?) for users who have more media in help articles.
