Rated 2 out of 5 stars
There are several reasons why I DO NOT recommend downloading this add-on:
1) The author fails to update the plugin.
2) It's buggy as all hell. It slows down your experience and the scripts don' always work as they suggest.
3) Updates. The authors of the scripts that TweakTube is using will ask you to update their script, but due to errors in TweakTube you will never be able to update anything.
Of course, #3 is a major issue because the author refuses to update his add-on. Since the author has turned away from his own creation I would suggest we do the same as the lack of support with this add-on is straggering!
