Visual Studio actually puts the menubar in the titlebar; I never have any place to click left unless the window is maximized (or, at least, full width).
I'm ok with adding more functions to the titlebar, it's something I experimented with myself for a desktop app some 15 years ago. I found there was a heck of a lot of special behaviours tied to the titlebar and that overriding them meant a lot of work to fix edge cases like - being able to move windows. So I never followed through with it.
Maybe the addition of dedicated Move button next to the minimise, maxmimise and close button would be a reasonable compromise?
That would provide a consistent target to click on with your mouse. Obviously a button is a lot smaller than the entire titlebar for clicking on, so there would be some efficiency loss for people that regularly move windows (I am one of them). Getting move use out of the titlebar space would be worth the minor inconvenience of a more accurate click-drag to move operation.
If you need to use the move button, the move button needs to stay on screen. I may be the only one, but I regularly position windows partially off screen when I only need one side of the window and I don't have enough desktop space for the whole thing.
Oh yeah, that's a little bit annoying. It looks like I can drag on the second toolbar on the very left but it would be much better to force some dragging space both left and right on the title bar. Otherwise I think menus there is okay, I don't need the entire title bar as a dragging area.
