 Command input works in both Normal and Visual modes, including read-only diff panes. The original selection stays highlighted while typing. Enter dispatches with its ranges, direction, and linewise shape intact; individual commands decide whether to consume or retain them. Escape returns to the original Visual selection without executing. For example, select lines with `V`, then type `:diff.comment` and press Enter—no command palette is needed. `config.core.command` can also be bound in Visual mode.
 
-Use `:!COMMAND` (for example `:!pwd` or `:!echo "$PATH"`) to run a shell command asynchronously while continuing to edit. Vamp runs `$SHELL -c COMMAND`, falling back to `/bin/sh`, in the editor's project directory with the inherited environment and closed stdin. Shell quoting, pipes, and redirection work normally; interactive terminal programs are not supported. Commands have the same permissions as Vamp, including file and network access. One command can run at a time; another `:!` is rejected until it finishes.

-While running, the default top bar shows the first three command graphemes, `...` when truncated, and an animated spinner to the right of the battery. Completion opens a read-only floating window with the command, exit status (or launch error), stdout, and separately marked stderr. Arrows/Ctrl+h/j/k/l and the mouse wheel scroll; Home resets, End goes to the last line, and Enter/Escape dismisses it and resumes the underlying editing mode. Output is decoded as UTF-8 with replacements; controls are displayed as text, never interpreted as terminal escapes. Capture retains up to 4 MiB per stream with an explicit truncation notice. There is no command timeout; exiting Vamp kills the running process group, and background jobs in that group are also stopped when the command exits. Shell execution currently requires Unix.
+While running, the default top bar uses one independently styled segment immediately left of the battery for all pending commands. Each entry shows the first three command graphemes, `...` when truncated, and an animated spinner after a 200 ms delay. Completion opens a read-only floating window with the command, exit status (or launch error), stdout, and separately marked stderr. Further completed results queue without replacing the visible window; Enter/Escape dismisses the current result and opens the next, or resumes the underlying editing mode when none remain.

 In the shell output window, your configured `config.core.word_wrap.toggle` binding toggles soft wrapping, including leader and multi-key sequences. Bindings use Normal mode while the popup is focused; there is no additional default shortcut. This does not change output bytes or the source buffer's wrap setting. Wrapping starts off for each command; toggling resets scrolling to the start. With wrapping on, vertical scrolling follows visual rows and horizontal scrolling is disabled.
