Wishlist: emphasize drag'n'drop feature of tracks

[ronso0]

Mixxx has a great feature which I discovered only by chance:
one can drag track properties like title, artist or cover art to other decks or to playlists and crates. This is great if respective track is currently not focused/visible in library table.

I don't know how this could be implemented, but IMO it would be a
huge help for new users if
a) mouse pointer changes when hovering drag'n'drop-able items
b) all areas where this item can be dropped on are highlighted
  (i.e. by a border) if mouse is dragging such an item

In some other soft they colorize the background color of the drop target, which is conveniently obvious.I´d prefer it over a tiny mouse pointer.

As a first step we could extend the tooltips of artist & title items like this. Currently they have the 'dropTracksHere' string attached, so something like the following would make sense:
"You can drag title/artist to other decks, samplers, as well as drop it into playlists and crates"
