Rated 5 out of 5 stars

Just installed it on 3.0.4 and it works great! I was looking for some tool to filter stuff with RegExp :-). BTW. I've just created a test search folder with Subject Regex Match and it seems to work fine. You just need to remember to use the Javascript syntax if you want to use case-insensitive search.

This review is for a previous version of the add-on (1.1.0).
