A model with other versions downloaded is one card with a numbered tab on its right edge; a click slides the versions out beside it, under one accent edge, the tab on the last folding them back. A pin on each picks the version shown when folded. Open models stay open, and "Open all versions" opens or folds every one. Replaces the version label menu.
