Fantastic add-on, I use it all the time, it's near perfection.

EDIT: they seem to have come back on their own.

Perfect add-on :D

It works perfectly.
In the Watched page, it still has to comply with the 6 tag search rule, though that's just e621 itself and not the plugin, in case someone wants to complain about that. As a list it functions perfectly though.
Could use e926 support though.
