Well - In my case I have a transparent toolbar overlaying the thumbnails (grid cells), and i need to manually adjust the scroll to index so it doesn't get overlapped with the transparent toolbar. Maybe I'm not seeing any obvious solution here - exposing the scrollView worked for me (yes, one can mess up a lot with this, but your framework is all about flexibility)
