Right, so it's a theming change, and has nothing to do with the widgets

Again, you made it sound like you wanted a new widget when you actually
wanted a group of buttons to *look* like they were related.

"Sexiness" isn't a good enough reason. Why do you use that widget in the
first place? Why not put radio buttons instead? (And this is a
rhetorical question for this list, as I mentioned, put this in bugzilla)

The point is that we want to have a trace with explanations as to why
widgets were added. My 2 last contributions in that space were the
volume button ("A lot of multimedia applications use copy/pasted code to
that effect, it works as a toolbar item, it provides consistent
behaviour and look across applications"), and a spinner widget (for
pretty much the same reasons).

At the end of the day, it could be a theming option you're talking
about, or a new widget (see the discussion between Carlos and Thomas).
For the latter, you'd need more than "it looks good".
