I was thinking about building a Personal Book and realised I was going to do so from a number of source files and that it would be useful to be able to re-order them so was going to suggest this feature should be added.
Then I found out that I can already simply click and drag source documents within the Builder.

But it would be nice if more than four lines at a time were shown, or if the list would automatically scroll when a title is being dragged. If there are more than a few items in a PB, it's difficult to rearrange them.
