I use Google Docs on a daily basis, and having real-time collaboration with colleagues is such a powerful asset. Recently, I coded 500+ line-long program (that worked great) with a friend in under 2 hours with Atom/Teletype... Something that wouldn't have been possible if we just sent saved versions back and forth to each other. No other program has integrated cloud Simulation, t-spline sculpting, 5-axis CAM, sheet metal, rendering, and etc. like Fusion 360 has... which is why adding collaboration in REAL TIME within Fusion 360 would be monumental, and would put F360 (at least, IMO) at the top of all current CAD programs.
Onshape has already implemented this (along with Branch/Merge functionality, which you guys should bring back) and their workflow is extremely close to what I'm talking about. This is quite difficult to code--especially considering integrating the timeline--but it would be beyond worth it.

Also, you could improve on Onshape's current workflow by showing what other users may be looking at. I could imagine something similar to Google Docs and Atom/Teletype, where other users cursors appear wherever they are editing. Instead, Fusion could have designated "cameras" for each user, with different colors. These cameras would be color-coded and centered on the viewpoint of each specific user. I've attached a screenshot showing how I think this could work.
I hope that you guys at Autodesk consider this and/or something is already in the works! I'd love to see this implemented, and I think the community would benefit too.
