Other modules (and gadgets) should be able to hide their interfaces when VisualEditor is opened - for example the Nearby pages BetaFeature (https://www.mediawiki.org/wiki/Beta_Features/Nearby_Pages) creates a blue button in the top right.
Ideally this feature should be able to know when it is in edit mode and hide itself.
Maybe abusing the action-edit / action-view classes would be useful here?
