I concur, VS Code is amazing, I've totally forgotten about that. TypeScript I haven't really used much, so I can't judge that, but now that I think about I do most of my work in C# and don't have anything bad to say about it, so that's also nice.

Most of O365 is fine, while still a little bit slower than anything else, but the Dynamics just isn't responsive no matter what network or hardware I'm on. It's a convoluted CRM. And I do have a new desktop that I bought a few months ago, and 1Gbps network, so none of that should be a factor.
