I understand the point. From my perspective, however, it boils down essentially to the philosophy behind the tool.I'm a bit against such regrouping since a lot users prefer mouse access and visual structure is important IMHO.
I regard dual pane navigators as the console on steroids - designed for superfast keyboard operation, requiring no mouse input at all (Far being the great example, including process list and heaps of plugins).
My workflow used to be to jump between INtelliJ and Far and that's about it. Everything else just slows me down.
If the philosophy behind Files is different - that's fine, but it needs to be thought through in terms how ti is different from all the other dual pane navigators that rely on mouse inputs.
I do not want to preach to the pope here - just my 2 ozzie cents. The tool is again far better than anything I have seen and CMD-F + Ctrl-T would probably work for me.
