That's a thing I like. Did you get users doing this kind of complex data manipulation? Or did them all just use the app as a simple note-taking app?
I've been making prototypes for a long time now to try to turn Trello (or make my own Trello-like app) into a "data-driven" collaboration platform. I think the idea is similar. My idea was to let people create magic Trello cards that would behave like database queries, or mapreduce views, for example, a card with some special instructions would show an aggregate value based on properties of all other cards in the board, or list; another magic card could show a list of links to some other cards, working as an index; that kind of thing.
From what you say I imagine your app is probably better than what I am only imagining for this Trello-thing. However, my idea was to have this for teams, small businesses and projects. Since I'm not used to note-taking apps, calendars, smartphones or anything like that I don't imagine a tool like this for my own "casual data" (but the name "casual data" is a good one, maybe you should use it more on your marketing efforts).
