Just saw the shared debug feature. Really really cool. Mind literally hit a breakpoint.

That's great to hear! We definitely believe that collaborative debugging is a critical component of being able to demonstrate/reproduce issues, as well as validate changes made during a collaborative/pairing session. We look forward to seeing how folks end up using it :)

Is there any plan on adding built in FTP capabilities?, I would love to get rid of my current IDE and use VSC but is a hassle changing the code there and uploading using some FTP client

Why not use one of the extensions? https://marketplace.visualstudio.com/search?term=FTP&target=...

Any chance of talking the UE4 teams into requiring VSCode as a minimum instead of VS?

Me and my colleagues are going to play with Live Share ASAP.
