I am also supremely space-constrained, but I also had no need to take my development device away from my desk. So I got a workstation and a KVM to switch between workstations, thereby needing only one keyboard, mouse, and set of monitors for multiple computers.

I went further than that, because I also needed to keep the desktop largely clear and the floor space used down to an absolute minimum. So I got a 60s “tanker desk”, and put a smaller office table on top of it. the computers all sit on top of the office table, up near the ceiling (and away from a lot of the dust!) and the monitors and KVM dangle down from beneath it. This leaves only the two pedestal legs of that office table and my keyboard and mouse as the only things “on” the top surface of my desk.

And ignoring the chair, I can have four workstations and six monitors within a 30×60 inch footprint (the tanker desk).

Personally, I prefer Omnivore.

I don’t care about any new tab features except making Tab Mix Plus work effortlessly in the current Firefox.

Right now it’s a game of restriction-whack-a-mole in trying to canopener Firefox into making TMP work again.

TMP is one of the main reasons why I still use any variant of Firefox.

Why the hell is it so complicated

One hell of a complex and crazy history in a very tiny space over the last two thousand years.

Hell, you could just cleave off the last thousand as a reference and be done with that. Although that does leave out some juicy origin stories.
