It would be great if we could enable restricted access to multiple groups, rather than just one. For example, I have a FAQ topic that I want 3 of my 5 departments to be able to view. Currently, I have to either allow all groups to see it, or just restrict to one group. I could create a group that includes the 3 I want the topic to appear for, but that makes group management really messy. Enabling multi-group restrictions would alleviate this problem.
