[This feature is not in Feature Requests at Garage]
It all is about being out of the module, which contents is playing.
1. It may be a popup, when changing tracks.
2. A button (it's even more friendly then just a popup) somewhere on the bars to show a popup (or whatever... e.g dock/window like "Loading" one) with information about currently playing track and in which module, 'cause sometimes I get lost, when switching through the modules, where track is playing (e.g. Playlist/Player or Music). Also that popup can contain some control buttons (e.g. Prev, Next, Play, Pause).

It's really nice. But in fact I was about something more specific. Like setting the keys for MPlayer (framedropping, OSD, etc). A kind of configuration GUI for backend parameters.

Also I figured out something more

1. Volume. It would be nice to load the last volume level at startup. And to have the same volume in each module (it logically comes from previous idea).
2. Equalizer... Would be nice. But I'm not sure about libs etc, that can be used for it.
