Comment 6 for bug 552539

Remi: keeping the icon slightly visible was also deliberate, because its still clickable to get the grouping menu.

So as a general point I'm prepared to accept the desire for fully hidden titlebars. I think it's a bit excessive, but whatever. However, I want to do it in a way that's sane from a usability and code complexity perspective and this bug seems like an idea place to discuss the possibilities.

I think my best suggestion right now would be:

 * Grouping menu appears in the context menu if the titlebar is hidden
 * terminal backgrounds get a subtle coloured tint to reflect group receive status (not transmit status, you'll be on your own for which terminal has focus).

I've not looked into exactly how easy the second part of that would be to do, but I'm pretty sure the first part is do-able without too much drama.
