Rewind Conversations, Effort Control, and Unified Settings

This release gives you finer control over how conversations flow and how the model thinks. Rewind to any earlier prompt to explore a different path, set reasoning effort per model, and manage all your preferences from one unified settings menu. Workspace initialization is also 88% faster.

Jump back to any earlier prompt in a conversation and continue from that point in a new session. Use /rewind to pick a turn, then branch off without losing your original thread. This is useful when you want to explore an alternative approach or undo a direction the agent took without starting over from scratch. Learn more ->

Control how much thinking the model does with /effort. Choose from five levels: low, medium, high, xhigh, and max. Lower effort means faster, cheaper responses for straightforward tasks; higher effort gives the model more room to reason through complex problems. Pair this with per-model defaults in cli.json so each model starts at the effort level that suits it best. Learn more ->

Access theme customization, keyboard shortcuts, and terminal configuration from a single /settings command. Run /settings theme to change colors, /settings keybindings to view shortcuts, or /settings terminal to enable Shift+Enter / Option+Enter for multi-line input. The existing /theme command still works as a shortcut. Learn more ->

Configure default settings for each model in cli.json that apply automatically to every new session. Set a default effort level, or any other per-model preference, so you don't have to reconfigure each time you switch models. Settings are keyed by model ID and merge with your global defaults.
