It disables Tab X Rated 3 out of 5 stars

It looks great and seems to work as well, however I've noticed that it will disable Tab X (makes every tab always have a close button) - if you can have a look at that bug, it would be great!

This review is for a previous version of the add-on (0.8.6). 

Split Pannel close button

Should have any problems with close button now as it uses separate imigenow.
