Yet Another WinDec I Drew But Didn't Implement (YAWIDBDI?)... anyway, this one is inspired by websites like mozilla.org that use those really cool rounded-rectangular tab thingies. They're so simple and yet I think they look really cool.
Attached is the Inkscape SVG file containing the drawing. If you've seen any of my other entries, you're probably aware that I have no QT/KWin skills and don't plan to implement this as a real window decoration. However, if y'all like it enough, I highly encourage some motivated soul out there to make this a reality.
