Stack Exchange tags sets : exclude tag

Here's my filter: https://stackexchange.com/filters/26689/mod-rewrite

That's pretty nice, but I'd like to exclude stuff that have the tag.

Sometimes (hopefully not often) I'm losing some time trying to read and understand questions I'll never be able to answer, and I guess maybe I'm not the only one in this situation.

So, the Stack Exchange filters options, there's the 1. Which questions do you want to include? and I was wondering: how about adding an option, or a sub-question... or maybe a 2. Which questions do you want to exclude??
