OpenTUI 2.9 beta.3

The current package is 2.9.0-beta.7. It ships a polished OpenTUI client around ordinary tmux sessions. tmux owns PTYs, processes, topology, persistence, and SSH; the daemon publishes semantic workspace state and pane streams; OpenTUI owns presentation and input.

Included

• Home, Terminals, and contextual Commands.

• Agent state in the sidebar, window tabs, and pane chrome.
• Agent-row navigation to the correct pane.
• Mouse and keyboard pane/window selection and control.
• Pane splitting, resizing, renaming, creation, and confirmed closing.
• Memorable names for newly created panes and windows.
• Indexed and truecolor terminal cells.
• Retained content through quiet panes, resize, theme changes, daemon replacement, and viewer reattachment.
• A downloadable, checksummed runtime for macOS and Linux on arm64 and x64.
• Detachable app hosting with tmux-ide app --detachable.
• Optional workspace-defined Files, Diff, Missions, split, and tab views.
• Rich Markdown, raster image, and structured card rendering in panes.

Deliberately bounded

tmux-ide web fails with an explicit message instead of starting an unsupported web client. The native desktop client is still under development. Mission profiles and the Missions panel exist, but public CLI mission dispatch from workspace defaults is not wired in this beta.
