Claude Code 3.0 is CRAZY!

I'll show the new session screen with recent folders, saved environments and a worktree per folder, then the biggest change: nested sessions that run tasks in parallel and send their results back to your main session. After that, I'll cover follow-up suggestions you can start with one click, the /btw side tabs, the new sidebar status groups, and the live to-do list, recap card and side rail inside a session. Finally, I'll go through what people are saying in the replies, the usage-limit problem, the new idle compaction feature from Lydia Hallie, and my honest opinion on the whole update. -- Key Takeaways: 🚀 The Claude Code desktop app update makes it easier to run many sessions at the same time. 📁 The new session screen shows your recent folders, so you can start a session with one click. 🧩 Environments let you save a setup, like a few folders, an SSH host or the cloud, with an optional worktree per folder. 🔀 Nested sessions run parallel tasks on their own and send their results back, so the main chat stays readable. 💡 Claude now suggests follow-up work while it works, and /btw opens side questions in their own tab. 👀 The sidebar sorts sessions into Needs input, Working and Completed, so one look tells you which ones need you. ✅ Inside a session, a live to-do list, a recap card and a side rail show the plan, the turn summary, the context and the changes. ⚠️ The replies are mixed: people want the effort slider back, and usage limits are the real barrier for parallel work. 🧠 Idle compaction summarizes long idle sessions right before the prompt cache expires, which saves some usage. 👍 Nested sessions and /btw tabs are the best parts, but the effort slider and the limits need fixing.
