The request should be like this:
Add a Scan option to monitor files added to ML every time BSplayer is opened (this will take some minutes to complete)
Add a Scan option to monitor files added to ML every time BS.MediaLibrary is opened (this will take some minutes to complete)
Add a Scan option to monitor files added to ML (actived by an appropriate button in Preferences -> Media Library window) when a users press the Scan Now button (maybe this button should be added also to the skins)
If also a default folders list can be setted in the MediaLibrary preferences window, all these scans can be performed only for that folders
