Funny and, for a gag, surprisingly thorough and complete.

Could you please allow closing windows by doubleclicking on the top-left(!) corner of a window? I kinda need that (e.g. this still works for the file explorer on Windows 7, even though there is no icon).

Since Windows 8 system menu icon reappeared in file explorer's titlebar.

Double clicking that button closes the window. Just tried on Windows 8.1
