Videos application implementation
Totem's UI is from another generation, being on of the first "developed for GNOME 2" applications. Its UI is getting rejigged following designer input: http://live.gnome.org/Design/Apps/Videos
Affected modules: totem, totem-pl-parser, grilo, grilo-plugins
The majority of the biggest UI improvements are there. Bugs and regressions are being fixed, and new features being implemented.
The current implementation lives in totem's master branch in the GNOME git repository.
