I'm running a board with very less need for moderative actions. Therefore me and the other moderators/admins doesn't look in to the MCP very often leading to having some open cases without noone paying attention for a week or so every once in a while. Therefore it would be nice to realize some kind of notification feature. The first thing I was thinking about is simply to display the sum of events of moderative queue/reported messages (btw: shouldn't be the reported message beeing a part of the moderative queue tab??) next to the MCP link, like:
Moderator Control Panel (5)
....that's kind of inspired by the unread PM count display
I also thought about other possibilities, like mail/PM notifications but these are probably less effective for boards with mod-teams since MOD1 might look into cases that already have been solved by MOD2. All in all a real-time count display of unsolved moderative cases seems the most practicable solution to me.
Since the average phpBB community is probably a small/mid size forum I can imagine that this might be useful in many scenarios.
