Scriv for iPhone - stack of index cards

I always liked the idea of a stack of index cards on my iPhone, so I could flip through them and perhaps update the titles & synopses, and also double-tap to edit the associated document. Access to document notes and the binder for rearranging things would be really essential, since I doubt I’d do much writing on that screen; I’d mostly be planning (notes, metadata, etc…) on that tiny of an iOS device.

I’d love an outliner (in theory… in practice, my eyeballs might explode from all the squinting), but I doubt it’s feasible on that tiny of a screen.
