Yeah, it’s mostly fine but a little half baked in spots. Just kind of perplexed why they would rush it out.
Speaking as a former MSFTie, my experience is that some orgs (like OSG: Windows) are more conservative with UI/UX changes (between major releases, at least) compared to others (like DevDiv: Visual Studio) and it's motivated by avoiding risk: i.e. "if it ain't broken, don't fix it, even if it is currently uglier than a mid-2000s KDE desktop".
