Review: Needs Fixing

One issue with the MR, otherwise looks great:
- in selection mode if you open a picture and then select it, we need to scroll that picture into view when returning to the Grid Photo Roll view. This works when not in selection mode (opening a picture, swiping through a bunch, then pressing the grid icon on toolbar)
