What puzzles me the most, that nobody managed to create highly customizable editor for websites. People have two extremes – create everything from scratch, or use some hardcoded solutions, mostly for people without any programming knowledge. So the whole niche is empty – for the people who have programming knowledge, but want this task done quickly and with best practices. This exact solution seems to be too complicated. It is promising, I agree, but without careful consideration of composability we might end up with another monster. Also, I'd like to notice that I think it should be extremely simple, and code should be hidden completely; though the idea of "marketplace" is amazing, because all components, basically, already exist.
