This suggested feature would add a “channel monitor” mode to the app. This would be a settings option that would allow the user to continuously monitor channel activity while the app is running on the phone but not necessarily when the app is being displayed or when the screen is on. I would suggest mirroring the function with the way any music app functions by allowing audio to play while using other apps or when the screen is off. Ideally this would include a persistent notification that would allow you to toggle the monitoring on or off in the same way that a music app would let you pause and play the music and a quick way to get back to the app and send a message. This control could also be available from the lock screen in the same way that a music app enables pause/play from the lock screen.
I don’t think this should replace the way alert notifications work but it would give peace of mind for those periods of time where you don’t want to miss out on any communication on the relays.
As additional channels are added, the persistent notification can be updated to display the channel that is being monitored and a control to change channels. A message button on the persistent notification to send messages without jumping back into the app would also be a neat feature.
An additional enhancement to this function would add an option to automatically put the app into channel monitor mode when an alert is received from a relay.
