First thing: I've used v6.4 of your front end and your mappoint integration is unrivaled. I haven't tried your v2 out yet (temporarily removed pc).
From what I remember there weren't any visualizations for music. Is this just the skin limitation or is it even possible for wmp vis. to be seen in your frontend? Also, have you thought about having a file browsing feature as well as the 'pop-down-search' feature (which is cool btw)?
Summing up my requests:
1- wmp visualizations support
2- file browser (expand on this maybe on-the-fly playlist?)
Just some ideas, thx for the great software btw.
