And right there is the problem.
"The app"?" Just one app? At a quick count I have 10 different "apps" (or programs, as we call them) running, in 32 windows, several of which have multiple tabs. So of course you need a decent OS (or window manager, as we call it) interface, unless all you are doing is "pissing" (as you call it) about.
