because it has a different API, and hence requires seperate routines to access winamp... it *should* be added for the next version, as well as wmplayer(basic reading only, use the windows media plugin for full support)...
also... other features im hoping to put in:
use of the publish thing to put some things into the 'plus/plugins' menu...
Add a window to show help/commands list (will be in the menu)
put a options screen, and have a favourites tag list / custom /xss commands to do the same as the commands you can make in the plus options (but have it in as options in the plus plugins menu)
edit: i may even put a ping command in
that uses the windows performance counters to time it, so you can get really accurate ping replies (it will be to other systemstats users only)
