Right; except sparkle is terrible. At exactly the moment I want to use the app I get bothered by a difficult decision: Do I want to interrupt the flow of my work and wait a couple minutes so it can download and update, moving something that should happen in the background into something that directly interrupts my flow. Or skip the update and hope there were no important security / compatibility issues fixed. (Or kick the cart down the road and have it remind me later.)

The button I want is “update in the background when you close the app”, and it shouldn’t ask; it should just quietly do that. For all that chrome’s updater is like a tropical disease, it sure has way better UX than sparkle.
