Notification look-and-feel

[gavv]

Currently we use notification with two small text buttons to stop sender and receiver. If the user started sender, notification will have "stop sender" button. The same for receiver. If the user didn't start anything, no notification is present.

Probably the following behavior would be more convenient:

• in the app UI, instead of two separate START/STOP buttons for sender and receiver, we can have one START/STOP button and two toggle buttons to enable/disable sender and receiver
• in notification UI, instead of two separate STOP buttons, we can have one START/STOP button, just like in the app
• we can make notification button bigger and use PLAY and STOP icons
• when the user presses STOP in app or in notification, both sender and receiver are stopped
• when the user presses START in app or in notification, we start what is enabled by toggle buttons
• notification is always present, even if nothing is running currently

Rationale:

• the user usually decides once what they need (sender or receiver or both) and then most times needs to start and stop them according to that decision; so it would be reasonable to have a quick button for that;

• one big button to start or stop everything is easier to use;

• if the user stopped everything via notification, chances are that they will want to start them back after a while, so it's better to keep notification.
