Two points: They keep changing the interface faster than I can learn it. The way to enable complex expression of tasks in a user interface is by composition.

Two points: They keep changing the interface faster than I can learn it. The way to enable complex expression of tasks in a user interface is by composition. ie have microtasks that you can then combine in different ways. That's what makes excel great - each cell is a single function but you can combine them to build stuff the developer never knew was possible. Being able to store state ( a location ) and then operate on that state is a pretty basic building block of a composable map UI.
