I'm curious how other teams maintain their "latest design" mockups for designs that have been shipped.Zach asks on GitHub: I've always wondered how Snapchat was able to get away with a design that broke so many conventions, particularly in the way you navigate the app. Overtime, they seem to have been returning to a normal nav pattern, especially now with the new tab bar design. What do you think of the app's design and evolution, and do you know of any other apps that break the rules and still find success?Mannnny asks on GitHub: Speaking of being a team lead or manager, what do you think are the core skills a manager should have? Also when do you know you’re ready to be a team lead or manager? Do you have to be a great IC to be a manager? I personally don’t think so, they’re very different roles and requires different skills.Cool Things:Brian shared Must, a prettier Letterboxd.
