Thank you for making this add-on! Although it does not have as great of a UI as compared to Tab Center Redux, it has many more options (and themes too!) and is more compact, therefore being able to display more tabs.
The developer's also quite on Github, having checked and labelled my feature request almost immediately.
Although it's been nearly half a year since this add-on has been updated (as of the time of writing), I'm looking forward towards the future development of this add-on!
