Try this simple test -
Create a view 'Published' with following sort specs
Make 'Published' the current view, and do some column adjustments -add, remove, move, etc.
Select
VM->Create new and call it 'Set Location'
Now go into
VM->Customise plugin, our objective is to adjust the sort sequence of Set Location so that Publisher ascending is topmost rather than Published descending.
When I select the just created Set Location View this is what I see
I suspect my usage patterns don't meet with your expectations of how and why the new features might be used. I enter all individual 'book' metadata via the book list. That is the main reason I create new views, by arranging the columns in the sequence that is optimal for the source - which are not commercial book publishers. Often as not I want to retain the current sort sequence.
