Just a minor cosmetic thing, but if you pull down on an ImageList from the top, keeping your finger down long enough to open the side context menu, the imagelist will "stick" when released with the blank white space at the top showing. See pic.
It actually might even be a good idea to disable the long-press for a context menu while scrolling?
I'm going to close this issue and mark it as a duplicate. This is currently logged under issue #370
