I get that. I just use an app that lets me maximize windows with a shortcut (I use Size-up but there are many great options). I then make sure to maximize everything, so effectively all my windows are always maximized.
It's not the same as fullscreen, because it still has the top mac bar, but that's fine, and it gives me the ability to cmd+tab / cmd+tilde through my windows.
Except for that annoying quirk, I actually find the interface better (though it definitely took time to get used to it).
