Auto Close for Tab Bar

[XenoPhex]

I was wondering if there was any way to auto close the Tabs sidebar when there's only 1 tab open. I've tried to figure out how to do this but I can't seem to find any option to do this.

I don't believe there is.

There isn't. I have requested this feature often, as have others.

Add me to the list. This seems like a simple toggle but I may be wrong.
