When I unfold a parent with subitems so that some of these subitems would be off the bottom of the screen, the grid is scrolled upward so that more of these items appear on the screen and the positon of the parent item in the visible part of the grid is changed. When I fold the parent again, its position reverts to what it was before. I find this very disorienting. Strangely, I have one grid where this isn't happening, not sure why. Anyway, I'd rather do all the scrolling myself - or alternatively if only the first jump in the grid happened (moving the item towards the top when unfolding) without jumping back to the previous scroll position when folding again, that would be fine by me. Thanks!
