Thanks Sean for the interesting insight! I'm brand new to so I have a lot more questions to your answer.
• "custom UI to represent my repeaters" - Does that mean not use Repeater.itemsLayout & Repeater.itemTemplate ?
• "display results in sections" - what would that look like with scrolling? (sorry, only sections I know is in HTML)
• How would I "Pop results in/out the viewport as you scroll" ?
Do you know where I might get more info (examples) on your techniques you're talking about?
Thanks so much for your thoughts.
