I was looking through a forum here and noticed that there were threads that I didn't want to see, but I did want to see everything else. Basically, I'd like to be able to click on a thread prefix and exclude it, instead of including only it. Sure, I could click each other prefix, read the threads, go to the next prefix, read the threads, but... not really that user friendly of an option I don't think. Design wise, I have no idea what would be the best way to do this, but maybe a "prefix" that says "exclude" and then any prefixes you have selected will be excluded instead of included. Click the "Exclude" prefix again and it's off and all selected prefixes as then included? I dunno, an idea anyway.
