Very simple, very compact xfce window decorations based on Smallscreen.
Warning: This is very compact, with a height of 7px, and will not accommodate most fonts, even at 6pt. I found a few that seem to fit, and have settled upon Nimbus Mono L Bold 6pt, which seems to work.
The GTK theme I am using with this is 'trinity' as can be seen in the screenshot, but this package contains only the xfwm4 folder.
I'm new at this so any suggestions are welcome.
