Hi zumer, here's some hopefully constructive criticism regarding this plug-in...
1) The website link comes across as spam-like as there's nothing on there to give an indication of file size, OS support or anything else. Without the context of the image & having done a search to find you'd previously posted this on the Winamp forums, I'd probably not have attempted to try it if I was a normal user.
2) The plug-in doesn't follow the library font styling so like in the image I've attached which shows the areas that aren't showing in the larger font I'd expected based on my user settings (the list is correct as the library plug-in handling of listviews is dealing with that correctly in this case)
3) The play / enqueue handling doesn't appear to be working correctly. I've got enqueue set as the default library mode & using the menus gives the inverted action so enqueue nuked my playlist (thankfully I can use the undo action to get things back). Double-click seems to be ok so something to check out.
4) The plug-in seems awful large (1.51MB for what it's doing). My version (see other attached screenshot) is ~100KB though I do have it using a shared copy of libcurl so maybe you've done the same but included it (or a comparable networking library, etc) all together which could explain it. However I just note it as the modern skin engine (gen_ff) is ~1.6MB & does so much more so there might be some optimisation / compiler options that can be tweaked to get down to what I'd expect a plug-in of this type to be more like.
Overall it appears to work & is a different take on how I've tried to do it with my initial version of a plug-in (which works on a local cache rather than live queries against the Icecast, SHOUTcast & Tunein services).
