Upfront theme editor - design on tablet?

Hey,

I am still playing with Upfront. And I know there is alot still in the works and to be released. But, I thought I'd throw this out as a possible addition.

Can we make it possible to edit (drag and drop) in Upfront on a tablet device. I just tried and it doesn't hold on.

Maybe this is already possible and someone can tell me how, but if not, I think it would really push Upfront way ahead of any competitors.

Thanks!
