When creating a BRIDGES assignment, I loaded two visualizations. The first is an Array2D, which does not enable the "Toggle Node Labels" and "Toggle Link Labels" menu options by default. The second is a BinTreeElement, which does enable those menu options by default. However, because the Array2D is loaded first, the options are inaccessible for the BinTree as well. When the order of the visualizations is swapped, the menu options appear because the BinTree is loaded first. For this specific assignment, the first order is essential, so a good feature would be to make these toggles available regardless of order, or only for visualizations that use them.
