I miss DabbleDB greatly.

I once made a real meals-and-visits schedule signup sheet app for a sick relative (dozens of folks signing up for slots over days, etc.) in about 20 minutes, including learning a bunch about the tool.

Ultimately it "just" made CRUD apps, but it made the process amazingly fast. The equivalent of updating a Django model and view was usually a click or two with no waiting, and the only typing was to name things.
