Great work. Thanks! Rated 4 out of 5 stars

But i hate the animated button, but definitely it's great and very useful tool.

Edit: You can switch the icon to a not animated button version. Sorry, my fault.

This review is for a previous version of the add-on (4.9.12). 

Note that from the add-on preferences, you can switch to a still (not animated) colored/grey toolbar button.
