Android has lots of places to do things. Lockscreen widgets, homescreen, app drawer, notification shade, google now...
To make things more simple (without removing functionality) is almost always a good thing. So what do you think Andoird could do to become more simple?
I'll give you two suggestions to get the ball rolling.
1) Unified messages app - messages, sms, google talk etc. all in one place. (filterable, of course)
2) Google Now combined with notification shade - still accessible across the system, notifications when you need them, notifications indicated in status bar, quick access to search box/voice anywhere without 'leaving' current app etc.
So, what do you think? How would you make Android more simple; without losing its customability and functionality?
