Current problem
Currently the only way to speed up the process of switching to another account in the quickswitcher is with the numbers 1-9. This is good, but usually another very intuitive way of navigating a UI like this would be with Tab or the arrow keys
Proposed change
The ability to use the arrow keys (tab does kinda do this already but it also tabs to the meatballs-menu of every account which kinda hinders you from using it purely for switching between accounts quickly) to move left and right between the focussed/selected account. Pressing the Spacebar or Enter could then complete the switch
Platform
macOS, Windows, Linux
