[idea] Wrap tabs instead of one line scroll

[iRonin]

idea / problem

Scrolling tabs is not really a great UX in herdr (being a TUI), I'd like to haver an option to show all open tabs wrapped at the top, to avoid scrolling. The agents side pane shows agents, tabs can be used for other things so number of tabs != number of agents.

requested change

Add a setting to wrap tabs on top of the main pane, instead of having them in single line scrollable.

why you want this

Would imrove UX.
