@info-creaticode I’m pretty sure the user is talking about Google Docs-style realtime multiplayer project file editing, with features like you being able to see the other user’s cursor, see them drag around blocks in real-time, etc. About priority, that shouldn’t be an issue considering it’s nearly impossible for two internet requests to occur at the same time that do the same thing, and one would come after the other, and if something’s already been done then it probably can’t be done again (depending on what it is). This would require websockets and definitely modifying deep deep deep Scratch internal stuff to handle extra cases and be compatible with dragging, which might very hard and unrealistic to do at the moment.
