On the commercial side there's Actual Tools' Actual Window Manager
which is their all-in-one tools for manipulating windows in all sorts of ways.http://www.actualtools.com/
I believe there may also be a non-expiring discount mentioned in the forums somewhere.
Actual Tools also has split up various parts into separate programs for those who don't need everything.
Sounds like what you want is their Actual Window Menu
which is described as...
"Add to any window's system menu a lot of new functions, such as Roll Up, Make Transparent, Minimize to Tray, Keep Always-on-Top, Change Priority, and many others."
That one sells for $20 whereas the whole suite/bundle is $50.
On my othere machine, back when v5.x was out, I couldn't part with the full amount so I bought Actual Window Menu. Some time later I found
the discount for the full bundle and went for it. There's a number of features I don't use or need though. So check out all the different offerings.
Some features overlap among the programs.
[heh, two replies were posted while I was composing. I'm just too slow.
