First a big thank you T.P Wang for releasing and developing this component. I ignored it for too long. Now that foo_uie_trackinfo_mod became problematic, I finally took the challenge and tried to master the mysteries of callbacks and repaint functions. It was to my best; I managed not only to mimic all functionality of my old trackinfo_mod trackinfo display, there is still much to come.
Here is my current "test" now playing WSH panel:
Maybe the code is for use to someone:

Next I plan to finally write a full replacement for my former fullscreen HTPC trackinfo displays.
