- Option to automatically remove unused ports in a mapping (or even across several mappings). This is known to speed up a mapping, but is easily forgotten during design.
- Lookup boxes should have a way to restore/resync ports with the associated table, i.e. after removing ports. Incidentally, why are these even "cut" (removed) at all? Why not simply let the designer mark ports as "unused" (disabled), such that they are still visible under Ports and thus easily restored?
