Gradient color fills for shapes.
allows a color fills that have gradients.
This is under consideration.

Gradients is the biggest thing I would like. Otherwise it good for working on the go. No replacement for Illustrator in the long run. Love this. I'm also making stickers to post as stock vectors and through services like cafe press

You can use shadows (with fill down to transparent) in order to create a similar effect to gradients or even simulation of lighting.
I need this badly!!
