I'd like to see ports for other mobile platforms (iOS, Windows Phone, Windows Surface). I'd prefer to write my mobile apps all in one FPL, and Chicken Scheme would be a fantastic choice.
I'd also like to see more effort put into simplifying the build-to-mobile-app process. csi/csc are incredibly easy and intuitive, and I'd like to see a similar tool for one-step building runnable mobile apps from Chicken Scheme code. Maybe call it csm (Chicken Scheme Mobile)?
