---BIG PROBLEM. SUGGESTION TO THE DEVELOPER:
For the loop button or any button, when you click on it, it stays exactly the same and you have no possibility of knowing if the button has been activated or not!! THAT IS A BIG PROBLEM!!
It would be simple to make the button of another color when it is enabled and keep it the same color of the other buttons when it is not enabled.
Or when I move the cursor over a button that I use, it would indicate enabled or not enabled for example.
I will change to 5 stars when a change to correct this problem has been made.
This addon works well, even the loop button works well too.

---Update on 08/11/2021: thanks to the developer to have fully corrected the problem I had stated just above. Back to 5 stars.

Thanks for sharing this addon. Dearly needed on youtube where I tested it.
