I don't know how to take this in. On one side, it's great to have a cross-platform GUI toolkit that's easy to use; on the other side, it feels like a React-like UI is contrary to the spirit of simplicity and resource efficiency of Go.

I'm sure it has its perfect use cases, though.

While I agree, that the virtual widget tree has a certain overhead, the typical desktop app you would create with Spot probably does not have 1000s of components—more like ten to twenty probably. Compare that to the immediate mode GUIs that currently are en vogue, that re-render all controls all the time.

Spot does not have any optimizations regarding render performance at the moment and it might never be necessary to add them.

On the other hand, due to the reactive programming model, I really like how state management get a lot clearer—especially when working with multiple goroutines.
