@Brent Jett I agree. Also applaud the Customizer team on their stellar work. I'm an Agile guy, but block features like Mutombo. Haven't read the Transactions doc, but I'm assuming Snapshots is a POC aligned in tandem. So yes, definitely forward-thinking. There's no doubt that WordPress will thrive downstream with new features and the creativity of its 3rd-party developers. As for the Custo's functionality: I personally glob it as an actionable module, since I've trained my clients to limit their Custo usage and to focus primarily on their content (aka: actually using WordPress, not fiddling with WordPress). So perhaps I'm slightly biased to new Custo features for now ;)
