A proper location to save Plugin Data & Settings?

@tt_su: Please,
(1) open Layout
(2) Edit (menu) > Preferences…
(3) Folders (tab)

Explain how your philosphy holds regarding the use of the second (user) paths in the “Templates” and “Scrapbooks” settings ?

AND… is there an official “position paper” on this subject in the KnowledgeBase or elsewhere ?
