I asked for four tab splits in
@phibrowser over a week ago and
@LiZhenrong82556 delivered!
It still needs some refinement. You should be able to open a link in the third and fourth split by right-clicking it. This makes it really easy/convenient to open splits when needed (see screenshot from Arc). Right now, dragging them in from another tab clunky and slows productivity down
Arc power users, Phi Browser is what you're looking for. Been using it daily for almost 2 weeks. It's much better than Zen IMO
