#cmux 0.62.0: Markdown Viewer, Browser Find, Vi Copy Mode, and Localization

Markdown Viewer. Open Markdown files in their own panel and keep them live with file watching. Notes, READMEs, and docs refresh automatically as the file changes on disk.

Find in Browser. Browser panels now support Cmd+F with inline find controls, so you can search long docs, dashboards, and issue threads without leaving cmux.

Vi Copy Mode. Terminal scrollback now has a keyboard copy mode with vi-style navigation, making it much easier to inspect and copy from large output buffers.

Custom Notification Sounds. Choose from bundled sounds or pick your own audio file so background task notifications are easier to notice and easier to personalize.

Expanded Localization. cmux now includes Japanese plus 16 additional languages, and a per-app language override lets you change the UI language without changing macOS system settings.
