This MR attempts to move all it can be move to
totem.ui file. The point is to facilitate to maintain
totem-object and, I hope maybe, to make easy the split between
For now :
The controls button
The main header
The full-screen header
Bacon video widgets (mainly signals)
There is maybe more I don't remember.
I'm not sure if this MR can be an opportunity to improve this widgets and to split the
GActionEntry between "app." and "win." for the menus. Don't hesitate to tell me.
