Current behavior

To support multiple views, elements are hidden if they do not belong to the active view. The implementation works but it is not as efficient as possible.

Expected behavior

Explore and replace the functionality explained to use GraphLayoutCache. From an early review, this class can replace the need for hidding and showing elements.
