I put together a simple TST hack / extension that puts recently active tabs in the horizontal space (with a "user-defined" timeout). Have been using it actively for the last few years.
It's nowhere near perfect (see comments in the gist), but I genuinely enjoy the paradigm of easy access active tabs alongside a full laundry list. I find myself reinstalling it on new machines as I go. It's also just a few lines of CSS.
That said, keen to try out the nightly version of vertical tabs. Tho I'm hoping my active tabs hack might work with it too.
