Claude Code desktop app adds detachable multi-window panes

Anthropic's Claude Code desktop app now lets you pop any pane out into its own window. The announcement gives the diff view and the terminal as examples: you can drag one to a second screen while Claude keeps working in the main window, then dock it back when you want. Sessions can also be arranged side by side or stacked.

The practical effect is more room to watch the work. Someone reviewing Claude's changes or following terminal output can keep that pane on another monitor without taking over the window where the session runs. This explanation is based on the announcement post alone; its attached video could not be retrieved, so nothing it shows was checked, and the post does not say which operating systems or app versions include the feature.
