New category permission : "Create and see"

Perhaps a search filter + minor change will give us a large amount of this request …

  • Allow users to easily create PMs to a group (without expansion hacks that are used with the @mention stuff) - never been a fan of the expansion hacks.

  • Allow for a search filter to:GROUP_NAME to see all PMs sent to a particular group in the full screen UI

Together I think this would cover the sentiment behind the original request.
