I have always just used ctrl + pgup/pgdown in Chromium for tab switching (same in Sublime). I am guessing OP is referencing the fixed min-width of the tabs though?

I know it is completely insane, but I have a strong compulsion to keep my tab count low. Once it starts approaching 7 or so, it is time to evaluated which 3 or 4 have to go.

Meanwhile I go look at someone else's monitor and they have 25 open all the time, and I can recognize some haven't been touched in weeks. I just think to myself "Clean up after yourself. How can you live like this?"
