I have sincerely been wanting a feature like this.

Add options:

When "skip collapsed tabs = off (Default on)", it needs options to re-collapse child tabs back into parent tabs when the focus is not on said parent tab or its child tabs.

Hot key that can be held or pressed to enable scrolling between tabs anywhere within the window (not just in the sidebar).

Enable some key to open a parent folder when scrolled onto (when focused on).

The scrolling speed doesn't seem to change when set to a lower or higher value. I see it is in ms, so does it just check for the input of my scroll wheel every "blank ms" and then execute?

(*Some of these features I have requested might be in the options on Tree Style Tabs, so I'll go look of course*)

Regardless, a much needed feature in Tree Style Tab. Thank you.
