need function to skip TST's dummy tabs.

It works.

However, I'd like to have the option to disable scrolling wrap-around (so that you won't return to the first tab after you scroll past the last one and vice-versa).

Edit: It was updated and now has an wrap-around option. Excellent!

It's been a pain not being able to scroll through my tabs when using "Tree Style Tab". I didn't realize that it played such a huge part in my workflow until I lost that ability when moving to the WebExtension version. This extension brings that ability back and works flawlessly. I installed it and it started working instantly, and I haven't had to give it any extra thought since then. Thanks for creating this Joshua!
