Make maximised window button controls appear in line with left window margin, use space above launcher for launcher toggle switch
I apologise for the lengthy summary, this is the first bug I've ever opened here.
And it is a bug IMHO, a design bug more precisely.
When using maximised application windows, and with the launcher being set to permanently show, the button controls intentionally don't show in line with the left application window margin, but above the launcher. I've seen that especially novice users are confused by the window controls being placed strangely away from the window to which they're supposed to belong to (even more the bigger the launcher size).
I understand that the devs want to have some coherence with the dash window controls being placed at the same spot (which now sport the same looks as the application window controls), but I think this only adds to confusion. Launcher and applications are just of a different kind.
My proposal is to use the freed up space above the launcher for an auto-hide/permanent show launcher toggle switch. This could provide for a quick and intuitive way to pin or unpin the launcher to the desktop - most novice users wouldn't know that they can also find this functionality in the system settings, and it would even be handy for the more advanced when they need more screen width once in a time.
