I really like this add-on, it's very handful for some things and I like the visual style and the many customization options it have.
But I have to say that there is a little problem: The Tabliss add-on is returning to its original state after a little period of time. Sometimes minutes, sometimes hours.
Because of that, I saved my configuration on my PC and have to import it often.
If were not for this issue, this add-on surely have 5-stars by my side.
