👌, Lots of Views, Better... Lots of Voice

I spent 2+ days at MS Build , myself & others test Win10 Insider Builds, some mess with Edge Insider Channels, Dev Track just received a new Build, Windows just went to a new Version, Edge GA just went to a new Series. Let's hear voices, not just see Views. There's lots of new (or coming soon) Features & Functionality to discuss. Comments, questions, likes, dislikes, where is this, what does it do, what can it do, what can I do, how does this work, how do I get there, what are good habits. Converse, discover, learn, ASK, suggest. Where are resouces, what are some good tools, do I need any... the list goes on & on. Spur some thinking. Be curious. Some thing MUST be new, unfamiliar or maybe even as yet unknow (to you). Don't be shy or hesitate to be heard & "Connect with Us". What's something recent you think is particularly neat? Cheers, Drew
