Switch to the first pane in the first window after start #2
Description
This isn't a "bug" as such, but this does work in a way that's not exactly how I want.
I assume that generally, you'd want the "most important" pane as the first pane in the first window, so after starting a session, this would be the natural pane to be the active pane.
Muxify doesn't do anything to activate a pane, so this is just fallback to tmux behaviour, which is, when a pane is created, it becomes active.
Should be easy enough ...
