Enables desktop tab dragging for this host and its floating windows.

Styles each floating root before content is transferred.

Saves the main layout and every floating window, including closed registrations, tab selection, splits, desktop position and UI size. Does not move panels. Call between drag/layout operations.

Unhooks dragging and returns floating content if the main host survives.

Returns all floating registrations, including closed panels, to the main host.

Explicitly opens a registered panel in its own floating window. Returns false when unavailable or during a drag. The same content instance is retained; a lone floating panel is simply focused.

Restores a workspace using the existing content instances. Invalid data leaves the workspace untouched. Returns false during a drag/layout operation or if windows cannot be created. Desktop windows require the main host to belong to an editor PanelWindow. This saves layout, not the contents of each panel.
