ZedX

A fork of Zed, the high-performance, multiplayer code editor from the creators of Atom and Tree-sitter.

ZedX is maintained by ccbox.app and includes additional features inspired by the ccbox TUI session manager for AI coding agents.

Modifications from upstream Zed

• Version suffix: all builds carry the ccbox pre-release identifier (e.g., 0.229.0-ccbox+dev)
• Rebranded as ZedX with app.ccbox.ZedX* bundle identifiers and channel-specific app names
• macOS dev installs bundle as ZedX.app
• Terminal as first-class center tabs with terminal-attached planning notes (see below)

Terminal tabs in the center pane

Upstream Zed opens terminals exclusively in the bottom dock panel. ZedX promotes terminals to first-class editor tabs:

• Terminals open as center tabs -- NewTerminal and NewTerminalInDir create a TerminalView directly in the active editor pane instead of the dock panel, so terminals sit alongside files as regular tabs.
• Welcome screen shortcut -- the "Get Started" section on the welcome page includes a "New Terminal" entry.
• Manual close confirmation only -- closing a terminal tab from the tab X shows a "Close this terminal?" confirmation prompt, while shell-driven exits such as Ctrl+D close automatically without prompting.
• The Item trait gains a close_message() method that any item type can implement to show a custom close confirmation dialog.

Terminal-attached planning notes

Each terminal session can own exactly one attached planning note:

• Attached to the terminal session -- the note is opened from the terminal tab header, shown in a right-hand split, and hidden whenever that terminal tab is no longer the selected terminal.
• Persistent scratch buffer -- the note uses Zed's internal unsaved-editor persistence, so the Markdown buffer survives app restarts without forcing a file save.
• Restored by terminal context -- the note is keyed to the terminal session and working directory, then reattached automatically when the same terminal is restored.
• Markdown editing -- planning notes open as Markdown buffers for planning, checklists, and agent coordination.
