How do I make my app pretty? I don't see a way to add background pics or even the built in button icons....
Do I need to export as web project and hand coed these things

Buttons and text area....for button I see Position, icon and theme are changeable but not font style/color/size etc...

I don't see a way to change text font size and style in an element. I see in the tweet example it says to change style and font size but does not say how.
