Docking: panels the user arranges into splits and tab groups by dragging tabs.

inline constexpr GGPanel Outliner{ "Editor.Outliner", "Outliner" };

dock.Panel(Outliner, [](UI& ui) { OutlinerPanel(ui); });
dock.SetDefault(GGDock::Columns({
    { 0.25f, GGDock::Tabs({ Outliner }) },
    { 0.75f, GGDock::Rows({ { 0.7f, GGDock::Tabs({ Viewport }) },
                            { 0.3f, GGDock::Tabs({ Content, Log }) } }) } }));

ui.Dock(dock);   // in the window's document, where the panels go

Layouts are named. "Default" is the one set in code; it can't be overwritten and is always available. Save() / Load() serialise every layout as hand-editable text:

using Animation
current
  window main
    columns 0.25 0.75
      tabs Editor.Outliner
      tabs Editor.Viewport Editor.Log*      (* = active tab)
layout Animation
  window main
    tabs Editor.Viewport Editor.Timeline*

Panels are referenced by Name, so a layout survives title and language changes. A layout that names an undeclared panel keeps the name and shows the panel once it is declared.

Classes

struct GGUI::GGPanel: A dockable panel. Declare as a constant; the strings must outlive every use.
struct GGUI::PanelProps: How a panel behaves.
struct GGUI::GGDockDrag: Drag payload for a panel's tab. Public so the host can route it between windows.
struct GGUI::GGDockNode: One node of a layout description: a tab group, or a split of child nodes.
struct GGUI::GGDockLayout: A layout: one root node per window. Windows[0] is the main window.
struct GGUI::GGDockLayout::Window: A window of the layout.
struct GGUI::GGDock::Part: A child of a split, and its share.
struct GGUI::DockProps: Properties of ui.Dock.
class GGUI::GGDockSpace: GGDockSpace: the registered panels and their current layout, across all dock windows.
struct GGUI::GGDockSpace::WindowInfo: A floating window, as the host makes it.
struct GGUI::GGDockSpace::PanelInfo: A registered panel, for menus.
