I'll add UI virtualization to the list of concerns, especially for list views with a lot of data. Creating a UI element for each item in the list consumes a lot of memory and CPU, so it makes sense to do it only for items in view + a buffer before/after. And recycle the UI elements as the user scroll. This becomes difficult with custom non linear and non fixed size layouts. It also complicates UI automation, accessibility and keyboard navigation.
