I'm having the same problem as AmazInky, tried hiding and unhiding the buttons several times, even removed and reinstalled the add-on, no luck. Still five stars though, even with the functionality somewhat kneecapped by this issue.

Edit: New update fixed it! thanks so much!

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.
