- Block reference Name (Misc) is editable: the dropdown re-points the insert to another definition; typing a new name renames the definition everywhere (record re-key, Block marker, every INSERT reference). Anonymous (*) and xref blocks stay read-only, with the same guards added to Scene::rename_block. - Custom single-control dropdown (text field + caret) built on the shared floating_below overlay so the list always opens downward, unlike iced's space-based menu placement. - Consecutive "<Base> X/Y/Z" rows (Position, Scale, Start, Center, ...) collapse into one expandable summary row across all entities; the expand state persists across rebuilds and selection changes. - The BEDIT block tab no longer offers the layout Rename/Delete context menu.
