None that I know of.
What helped me the most about Tab Groups was not just the tabs organization, but the face that I could create regular expressions so that a new page would automatically open in its own tab group (and everything else in one 'Default' tab group). That was a killer feature!
I cannot stress enough how it helps me to switch between contexts. It's one of those things that you just did not know that you needed so much.
What options do we have?
