I like how Graphene looks well enough, but if Graphene is ever to be expanded beyond merely responsible people, all the way to normal people who would way rather one shiny useless app they really like the way it looks than any consideration of privacy and security, and since we need them to join too if we're ever to patch up our security vulnerabilities that come from having normal people as contacts, please consider making pretty apps.
Here are some apps normal people need: A pretty display on the lock and homescreen, which has a nice clock size of letters, and a weather app.
On the homescreen have the same thing, with a pretty weather app like Samsung has.
Make the launcher buttons have pretty cute versions (which you could toggle on with a thing in settings), like Samsung has.
With these small options, it would be much easier to get people to use Graphene.
