Is your feature request related to a problem? Please describe.
Currently the client frequently has to check for changes on the server creating high load also for idle files.

Describe the solution you'd like
The notify_push app can solve this problem by pushing the changes to the client directly via a websocket. Therefore the latency will be highly reduced making the app even better for collaboration.

Additional context
The notify_push app is already used for file updates which are often even faster than the syncing of the text app.
