By default I dump everything into the Global Inbox, or the root level of the database.
Then I work through the Inbox to get to inbox zero–and the root level of a database until everything is filed into a group (this stems from habits learned using ProDOS 8 on my Apple II when younger–never keep anything in the root prefix!).
OR, if reorganizing a group structure, I rename the old group OLD Group
and the new group Group
and then work through OLD Group
until it’s empty.
