Ah-ha - you've answered my question
I have three libraries (books, periodicals, audio video). Because that custom column order tweak is global I couldn't find a workable compromise - so I cleared it. Consequently all my long-text columns are shown below the other column types.
It was one of the factors that lead me to doing all my metadata in the book list. To that end chaley made a number of enhancements for me, including: '=' and '-' to set a date to Now and Undefined, ' ' to set an integer or float to Undefined, Shift+F2 to pop the Tag and other category editors etc.
Now, my only use of Single MDE is to cut content from Comments and paste into Blurb
