This service manages shared state between *instances* of recent lists. The
|
|
|
|
recents controller will hook into this central service to get things like:
|
|
|
|
- which rooms should be highlighted
|
|
|
|
- which rooms have been binged
|
|
|
|
- which room is currently selected
|
|
|
|
- etc.
|
|
|
|
This is preferable to polluting the $rootScope with recents specific info, and
|
|
|
|
makes the dependency on this shared state *explicit*.
