What's the point in making suggestions? Still have to go right into sound settings to turn ringtone and notification sound down. Each have to be done separately. All you have to do is add an option to link them both together.
Example I'm going into a meeting I want my phone to be quieter not dnd but just a lot quieter because I'm expecting a call but I don't want to disturb others in the meeting. So no I cannot link them both together like a simple turn them both down with volume rocker. I need to press volume rocker turn ringtone down then press volume message again and then turn notification down too. In custom ROMs you can toggle a switch to link ringtone and notification together so when you turn ringtone down the notification goes down too. Why would you only turn one down? But not the other?
Si now I have to install a separate app to do something that could have been implemented. It's supposed to be a smart phone! Not a unsmart phone. Yes I understand why flashing a custom ROM is the way forward
If anyone is interested there's an app which does this called volume sync
