For web apps, spinning them into “installed” apps (doable in both Chrome and Safari now) is the move. This unclogs your tab bar, gets rid of the pointless persistent browser chrome, and gives you the benefit of OS task management capabilities.

You can add Shift to both Command-Tab and Command-` to move in the reverse direction.

Also I find the default Command-` to be unintuitive, especially on non-US keyboards (` is next to left Shift for me). I remapped Command-` to Option-Tab so you only have to move your thumb.

Woah, I did not know about this installable web app feature - this is a game changer. Thanks for sharing.
