# tui/pop-out Pop a panel out into its own OS window. The app keeps its runtime, focus, taskbar identity, and panel id; dock it back with `tui/dock-back` or the window's ↙ button. ## Syntax

[tui/pop-out]
[tui/pop-out ?panel-id-or-tag]

## Parameters - `panel-id-or-tag` — number id or string tag (optional, default: the calling panel) ## Examples

[tui/pop-out]           # this app's panel
[tui/pop-out "editor"]  # another panel by tag

## Returns bool — true when the pop request was queued for the host main loop. False when no workspace is attached, pop-out is unavailable on the host (`retra`, `hydra`), the target can't be resolved, is already popped, isn't a leaf, or has no app thread. Popping the last grid panel is refused by the main loop. ## See Also `tui/dock-back`, `tui/close`, `tui/split`
