Our team would love to see the collaboration workflow improved as well. We are nervous that if we are working on the same prototype simultaneously and one we both save our work, that someone's work might get overridden. So our fix has been to duplicated the prototype and then combine the two together later.

Mijntje Kranenburg By "working together in the same space" are you referring to multiple users editing the same prototype simultaneously, with real-time updates visible to all editors in the file?
