Right now if you're supporter and come to spectate somebody, if they play a map you don't have it downloads it automatically upon request and then resets the spec without requiring you to manually reset it. That's a really nice feature.
However, if somebody is playing a map you already have, which is pending and got updated, it forces you to go out of spec, update manually, then return. This feature request is asking to make updating automatic - i.e. if the person you're spectating plays a map ID you already have but you either have a not-up-to-date .osu file or lack the .osu file (new difficulty was added, or rename) the game would update/download the required .osu on its own.
