Android 8.0 - What did they miss out and what would you like to see in Andorid 9.0?

So Android 8.0 is rolling out.... Great! But what's still missing that you guys have been waiting for? Personally, I would like to have custom notifications - i.e. what the notification looks like, what times and days I receive notifications from certain apps etc.

If you are unsure of what is being updated/added to Android Oreo - take a look here:
