Comment 6 for bug 1061684

"How is clicking on rythmbox from unity "harder" and requires a special area in the taskbar ... whereas opening up the settings and waiting for it is "easier""

My first reply wasn't as clear as it could have been. Although I think you miss the point of the rhytmbox shortcuts it is as you say not that usefull for opening the application but IS very useful for switching songs without having to switch from your current focused application, this workflow is likely to happen many times in one user session where as changing output is a once off thing.

I very much object to having settings like this added to the applet as they will make the applet crowded and are of no use to the majority of users. Also gnome-settings provides a simple centralized location for all settings I don't think its a good idea to start moving settings to other locations on the desktop.

Although you don't seem to realise it your actual problem seems to be two other things.
1. the gnome settings window is slow to load on your system (on my desktop pc its instant)
2. there's no auto detection for output.

based on your comments it seems likely that if gnome-settings window loaded quicker for you there would be no need to add this to the applet.
