Questions regarding Sync

[withsilentwings]

By searching I was unable to find "newish" answers on the following:

When using Winamp to sync to Android, does it update playlists and ratings both directions? For example, I have my music on my server which serves my various PC's and devices. When I sync to my Android device, the music appears to have it's ratings intact. If I take my device and rate a song 4 stars, next time I sync with my server will it change the rating of the server's copy?

Follow up question to the first question: I have the sync set to sync everything UNLESS it has a rating of 1 star. If I mark 5 songs with 1 star on the device, and plug back in to sync, will it automatically remove these 5 songs as the no longer fit the syncing criteria?

Second last question: I noticed wireless sync does NOT preserve ratings... Why?

Last question: When will Winamp Pro--as purchased on Android--let me see ratings and rate music? This is a very important feature to me, and despite paying for Winamp Pro, I cannot use it because it lacks this function.
