Hi Unity Design,
for consistency
window controls are always visible and apear by the left of the title in
non-maximized windows, so they should be always visible and appear
there too in maximized windows
for discoverability
google mobile is going to use three horizontal lines to represent a list
and shows the Google service and product list when clicked, so instead
of showing the menu bar for a few seconds, then hiding it, we could use
an icon with three vertical lines inside a circle by the right of the
window
title that represents a list and shows the menu bar when hovered
Best regards,
Pedro Bessa
