Cursor 3.11's Side Chats Ship the Same Primitive Claude Code Calls `/btw` — Convergent Design in One Week
Cursor 3.11 (July 10) added side chats invoked with `/side`, `/btw`, or the plus button, each a durable full agent conversation that can be revisited and referenced to pull context back into the main thread. Claude Code v2.1.212 (July 17) simultaneously changed bare `/btw` to reopen the side-question panel on your most recent exchange for browsing earlier answers — identical slash command, identical concept, one week apart. Two independent teams converging on 'context branching without losing the main thread' as a named primitive suggests the single-linear-conversation model is genuinely the constraint users hit hardest, not a UI preference.
