Sync (Android/iOS) via push messaging (GCM)
Currently, having added/changed tasks on one device is not immediately propagated to other devices/desktop.
This is really inconvenient as the user must launch the Wunderlist app (on e.g. a smartphone) so that the app can perform the sync and pull the newly added task (via e.g. desktop browser).
The sync should be done in the background and immediately -- via a push service (think: GCM).
This is why I switched to Todoist. :o( I don't like having to keep an app in memory just for active sync.
yeah, please enable this ;D
