Thanks for this detailed experience sharing, one question, so after ' ...The gatekeeper pastes the new artboards in to the master, examines/tweaks them as needed, and notifies team that a new master is available....' Are all of the team members delete their duplicate old library files, and then download new one and keep working on it? Thanks!

I actually emailed Invision team, they said it is not possible at the moment. However, they are receiving similar request lately, so if more request coming up, it will be convincing for them to develop such feature.

Speaking for myself, it is more realistic to merely focus on one area instead of two. Being expert in both is just too much for me I guess ╮(╯_╰)╭

But I do agree that basic coding knowledge is helpful. So it is more a question like how to be most cost-efficient to play with both code and design. AKA what are the minimum coding skills that I need to know in order to achieve a better digital design or communicate with devs more effectively.
