The save sheet gets "+ Previous page" / "+ Next page" (right to left for rtl in Page/Book) for a picture that runs over several pages. Moments store a layout (row | column); pages the selected region does not touch are dropped. Crops, viewer and gallery draw both layouts. Dialogs now clean up directly instead of waiting for the "close" event, which a backgrounded page can deliver late (a closed sheet stayed in the page and M stopped working).
