Add a new action to just select prev and next panes

Not exactly

Describe the solution you'd like
Creating new action(s) that lets people navigate through prev and next panes. This will allow people to just bind two keys to navigate through panes, instead of mapping four different ones. Most people like me with small screens will just use two or three panes at max. So an action to just cycle next/prev panes seems like a good feature to have.

Describe alternatives you've considered
I don't know of any

Yes, this will be very helpful. I think it will be enough just to add two new ActivatePaneDirections: Clockwise and Counterclockwise. Or just Next and Prev (sorting by creation order).

You can use wezterm.action.ActivatePaneDirection 'Prev' and wezterm.action.ActivatePaneDirection 'Next' to achieve the desired result.
