VSCode is fine, not great. Nice scrollbar. Still rather mouse dependent, not enough keyboard navigation (e.g. for git, AFAICT), and tabbed layouts don't use large monitors well. I like many files visible at once to see context.

Re:extensions: great when they work well. But they tend to move fast, and come and go fast. That makes combinations of them brittle. If they're conveniences, that's no problem. But if they're necessary parts of my workflow, then life can suck.
