The UI got a massive overhaul in the new Xcode beta. It’s no longer confined to the sidebar.

Devs continue to be tricked by incremental updates to it. It's still deficient

I love how it doesn't even support reasoning output or edit tool diffs. (Yes it can show diffs sometimes when using the 100% official flow but not when using ACP)

It also doesn't support Computer Use or Browser Use among other deficiencies

Sure but the basics should be down before tackling those, and they're not.

You call it solid foundations, I call it deficiency and being over a year behind state of art available elsewhere (from the same service you're already paying for)
