It is very simple but powerful in right hands.
Helps me to bypass one site's anti-adblock mechanism.

One annoying thing in filter editor: it disables filter after save and I have to either close editor or go to options and enable it. It would be great to have "Apply" button in the editor.

One more note: it would be good to have a link to regular expression guide/howto/short description. Or at least say what kind of regexp supported.
