All too often, when I am working on an item, for example; an image in first item in a repeater. When I try edit that item, EditorX jumps to a different item in the repeater.
On placement and sizes: I align an item to center, then EditorX changes the height and or width of image and moves it, so it is no longer visible. To see it, I have to give it height and or with in inspector and hope it displays on layout.
Grid change and image change setting popup is created out of current, on screen layout view. I have to scroll up or down to find it.
