Also keep in mind that the uuid id only gets generated when splitting files that use the stock SectionXXXX.xhtml naming pattern (with the Split at Cursor feature). And even though it's a perfectly valid id being generated, it can be avoided if you want by renaming the file to something else before splitting, and/or using the Split at Markers feature instead of Split at Cursor.

The uuid is just a necessary evil to programmatically ensure uniqueness in that very, very particular situation.
