Your goals are worthwhile. I recently built a tool not unlike yours, sharing many of the same goals vis-à-vis ease of use. Unfortunately it's currently closed source, but hopefully it'll be opened up soon and we can compare notes. There is definitely space for tooling which trade flexibility for ease of use. I wouldn't worry too much about Domenic's flame bait anyway, he has a habit of missing the point. (I mean, he did champion JS promises after all..)
