Collapsible Activity Feed

To make the Google Drive Activity Feed a bit easier to browse, it'd be nice if we could click to collapse events into smaller rows. If you're auditing your company's recent Drive activity, it'd make it much easier to navigate.

By splitting each action into a "header" and a "body" section, it's easy to conceptualize a "collapsed" view for the Activity Feed.

Working prototype:

I'd like to try to build a working prototype of this idea. First I'll need to research whether or not there's a Google Drive API that allows users to pull data from their own Drive's, then I'll need to try to rebuild the existing user interface with the collapsibility functionality as described above.
