Tag user as troublemaker highlights all his posts red

[sross]

I have a large userbase and sometimes it gets hard to keep track of the troublemakers. I noticed how when you select a thread as moderator in 3.4.5 it highlights it yellow. It would be great if there was a mod where you use that technology to keep a closer eye on troublemakers. It would work like this.. you open modcp, click a link called "troublemakers", add a username to that list. Now when you and your mod staff are going through threads these troublemaker posts are highlighted red (only the mods see this). It's just a visual indicator to say 'ah, let me make sure this red post isn't causing problems, etc. I hope someone thinks this will be worthy of creating. Thanks!
