API request: Get notification when syncing to any physical device

[CharlieJiang]

Hi. I'm working on a plugin to sync .lrc lyrics to the connected device(because Steven seems not to want to add this option).
So my plugin need to be notified when syncing a track from the lib to the device.
The event should called every time before or after syncing a track file. Like this:
public delegate void TrackSyncDone(string trackName, string path, string pathOnDevice);
And i should be able to write my plugin with it.
Thanks!
