Annotate AI Diff, Linear Integration & Claude Account Switching

Features

• Annotate AI Diff — leave comments on any lines of an AI-generated diff, then send them all back to the agent in one batch to revise, keeping the review loop tight without copying line numbers
• Linear integration — browse and create Linear issues alongside GitHub, with a team selector and persisted last-used task source
• Claude account switcher — hot swap between multiple Claude accounts, matching the existing Codex switcher
• Cross-group tab drag — drag tabs between split-pane groups, not just within them
• Per-tab activity indicators in the terminal so you can see which sessions are working
• Writable issues page with inline editing
• SSH status surfaced directly in the worktree UI, plus a streamlined add-repo flow
• Windows default shell setting to pick between PowerShell and CMD
• Update card now collapses into the status bar instead of taking up permanent space
• Blank workspace names default to a unique marine creature

• Polished sidebar typography and compacted the Task page chrome
