Show buttons on hover for extend text area with song info

[MurzNN]

At now widget button always visible, so they eats space in widget and cut text with current song info. Will be good to implement mode for show only text info in widget, but on mouse hover - show buttons (pause, and next/prev/stop). This will extend area for displaying current song info, and allow to show more buttons on "Play/Pause and track info" mode. What do you think about this idea?
