As described previously, I decided to create a custom widget script to replace the game launcher's HTML panel. The results are already looking awesome! The UI looks really slick. It's great to see this idea come to life in such a striking and attractive manner.

What's really cool is the OS drawing commands are being used, so the games grid uses cleartype subpixel antialiasing, and the UI is completely solid with no flashes or little visual glitches.

Oh, and except for the window titlebar and frame, this will look exactly the same on Linux.
