Clickable list of open windows to switch between them

[antimora]

What are you proposing?

A clickable list of open Zed windows, always visible in each window (for example in the title bar or status bar): one icon or chip per open window, showing the project name, and one click focuses that window. The current window is highlighted.

A keyboard version would be a nice extra: a picker like the tab switcher (ctrl-tab) that lists the same windows.

Why does this matter?

On macOS, cmd-tab switches apps, not windows. With several Zed windows open (one per project), getting to a specific one means going through Mission Control or the Window menu, or the mouse. The macOS cmd-` shortcut that cycles an app's windows does nothing in Zed (1.27.0, U.S. layout, no window tools installed), so there is no keyboard route either. That breaks flow many times a day. A visible list makes every open project one click away and shows what is open at a glance.

Are there any examples or context?

• Browser tabs and the macOS Dock: everything open is visible and one click away.
• The tab switcher already does the keyboard version of this for buffers.
• workspace::ActivateNextWindow / ActivatePreviousWindow exist, but they cycle without showing where you will land, and binding them to keys was reported as not working in workspace::ActivateNextWindow / ActivatePreviousWindow actions not dispatchable via keybindings #56163 (closed as not planned).

Possible approach

A title bar (or status bar) item listing open windows: project name, optional per-project color or icon, most recently used first, overflow into a dropdown when there are many. Clicking an item activates that window. The same list could back a workspace::ToggleWindowSwitcher picker for keyboard users.
