It looks like getting the apps built with this to work well on mobile is in the roadmap, but not mobile editing itself:
"A hand-sized touchscreen is too small for editing Scrapps comfortably"
I would encourage them not to underestimate the tenacity of mobile phone users!
For a lot of people these days their mobile phone is their only digital computing device. People write code on mobile phones. People write entire novels.
I think this tool's impact could be greatly increased by taking the time to figure out a mobile editing interface, even one that feels less comfortable than the desktop experience.
