We have a regular need for a non-grid scroller that scrolls over a list of items, virtualizing the instances of the item renderers. The grid does this of course, but it would be quite a hack to implement this for non-grid situations such as a list of cards or panels. Ideally this would work similarly to the grid and support infinite scrolling via the calculated dispatching of pagination events. Also would be great if it supported variable height item renderers.
