Coloured Threads?
 

I'm trying to find a plugin (if there isn't some functionality I'm missing) to enable me to flag threads as special/important so they then show to all users highlighted in a colour.

Ideally I want to independently tag threads and then have a background colour associated with those threads when viewed in the thread listing. Or alternatively a different icon at the front.

In the interim I have worked out how to colour the stickies, not exactly what I want, but something to keep me going while I investigate further.
