Right now we have move commands for items and move commands for lines.
The difference is that the “item” variants move the item, together with it’s sublist if present. While the “line” variants move only the selected items, leaving the sublists in place. This is complicated by the fact that the “line” variant will also move the sublist if it’s been collapsed. I think this is to much variation to keep track of.
I think it the “line” variants are most useful for TaskPaper. And you can always replicate the “item” behavior by first selecting the item together with it’s children, and then use the “line” command.
So my vote right now is to just include one set of “move” commands that work on lines.
