- Text changes
- Show channels on the app settings screen (again)
- Hide most of the channel settings under 'advanced' (note: this hides
the footer preference(s) also, at the moment. the functionality
to exclude those is coming in a later cl)
- Add a 'show notifications' toggle for each app created group
