Terminal tabs, panes, and windows are viewing containers; they do not create process or environment isolation by themselves. The shell’s working directory, credentials, and remote host remain the important execution context.
Tabs for sequential work
Use tabs when several shells belong to one project but only one needs attention at a time. They keep the desktop compact and make it easy to retain a server, test shell, and general command prompt. Give each tab a visible directory or process clue and close shells that no longer serve the project.
Panes for simultaneous observation
Split a Terminal window when two outputs must remain visible together, such as a development server and its test run. Apple Terminal provides a split-window command, but a pane remains part of the same window. Keep the pane count low enough that output stays readable.
Windows for independent placement
Use a separate window when contexts belong to different projects or environments, must sit on different displays, or should appear independently in window switching. Apply a profile or title that shows the host, directory, or environment. A separate window still does not prevent commands from targeting the wrong system.
Wallo can organize terminal windows as macOS windows, but it cannot see or group individual tabs or panes, validate shell state, or distinguish production from staging. Keep critical identity in the terminal itself.
