Currently the only way of reordering statements and qualifiers (for example, to order values chronologically for each property) is to delete all the affected things and add them back again in the correct order. Having options to drag them around/move them up and down to rearrange them would be very useful.
(I'm not sure if properties have a sort order, aside from grouping of identifiers, but it seems random. I don't really know how that works.)
