Claude Code App Redesign Brings Parallel Sessions, In-App Editor, and Rich Previews

Anthropic redesigned the Claude Code app with multi-session parallel work across repos, an integrated terminal, an in-app file editor, and expanded HTML and PDF preview capabilities.

Anthropic rolled out a redesigned Claude Code app that reframes it from a CLI companion into a full developer workspace. The biggest shift is the new interface, which lets developers run multiple work sessions in parallel across different repositories without juggling terminal tabs or separate agent windows.

Key additions in this release:

Parallel sessions: each repo gets its own tab, with its own agent state, model choice, and command history. You can kick off a refactor in one repo, a migration in another, and a review in a third — all running concurrently.

Integrated terminal: a first-class terminal panel sits alongside the agent chat, so you can inspect processes, run ad-hoc commands, and steer the agent without leaving the window.

In-app file editor: Claude Code now includes a lightweight editor for inspecting diffs, tweaking files before accepting an agent's changes, and doing quick edits without opening a separate IDE.

Expanded previews: HTML previews render inline, and PDFs generated by the agent — reports, invoices, diagrams exported as PDF — can be viewed directly in the app.

Together, these changes turn Claude Code into something closer to a dedicated agentic IDE. Teams that had been stitching together a terminal, a chat window, a diff viewer, and a browser preview can now do all four in one app. Anthropic has framed the update as part of its broader push to make agentic coding the default mode for serious software work on Claude Opus 4.7.
