Alright, but that's for another patch. Currently it only shows name that exposes \
model.

It is possible, but as the streams are now displayed in separate tab, I think it \
would be extra awkward. First you will need to change the tab by dragging the stream \
on the "Devices" tab and then you'll need to find the right device. As the systemtray \
popup is small, if you have more devices then you would need to also scroll the view. \
It is also much faster with the combobox than dragging.

In other applets (print, network, bluetooth, ..), we already have the pattern of \
showing additional options when clicking on item. So maybe remove the arrow and \
indicate the additional actions with hover highlight (as in network applet)?

Oh and also currently there is issue with scrolling of the view with mouse wheel that \
will be interrupted by volume sliders (or even may accidentally change volume). So \
I'm thinking of completely disabling scrolling with mouse wheel (as there doesn't \
seem to be better fix while having the option to change volume with wheel on \
sliders), which would make the scrollbar and flick with left mouse the only way to \
scroll it. And that would make the dragging impossible.
