#1 Could you add buttons in title bars?

[dr_wily]

Hi there. I just downloaded your app and I love it!
So far it hasn't crashed on me, hehe... Originally, I
was searching just for an Always on Top feature, to
make The GIMP more usable, and I was pleased to find
the Transparency option as well! Very cool stuff!

I'd like to request that you make it so that new
buttons are added to window titlebars, so that
accessing the features of your app would be a lot
quicker. That way you wouldn't have to right-click to
access the features: there'd be a button for
transparency (it would display a menu when clicked,
from which the user could select the needed
transparency level); a button for toggling Always on
Top (it could appear pressed in when it's active, and
normal when it's not, for example); and a button for
each of the other features.

It would also be nice if the above-mentioned buttons
could be sized dynamically to match the height of the
titlebar that contain them. This is important because
some apps, like Photoshop, resize some of their
toolbars to have titlebars that are less tall than the
default, so a smaller button would be needed.

If you wish, you could also make these extra buttons
optional, so that users aren't forced to have them.
They're just something I'd really find useful.

Let me know what you think, thanks!
