An option to use stock GTK+ close buttons on tabs.An option?!
Anyway, Totem's playlist parser is now ported to GIO. I'll make a release soon, but I'd like to ask people to please test the hell out of it. If opening or saving a particular playlist produces warnings, errors, or crashes, please file a bug.
You can test easily by recompiling and using as normal: Rhythmbox (Podcast and playlist parsing, playlist saving), and Totem and its web browser plugin.
