A couple questions about the grease pencil...

I’m mostly a Toon Boom user for 2d. But since it isn’t portable, I can’t really do anything away from my main computer. The grease pencil is pretty nice but it is missing a few basic functions that would make it very nice to work with more.

First, is there any way to render a drawing without having to convert it to a curve and assign some sort of mesh to that curve?

Secondly, is there any way to fill a drawing with a texture or solid color without having to make it into a mesh and work the materials?

Thirdly, can the onion skinning function be adjusted to show more frames that what it does by default?

Thanks for any help you can throw my way.
