It would be very nice to be able to assign a numbering scheme per file category. That way if certain files need to conform to a particular naming scheme, they can. Others might be able to be manually numbered.
Autonumber on check-in would also be useful. If someone is working offline (in the field or at home for example), when they get back on the network they could check in the files and choose between the available numbering schemes for the file category that they chose (or was selected for them).
Being able to AutoNumber the members of a table driven model would be very useful.
An add-in that would allow a unique property to be generated and assigned would would allow movement away from the requirement for file name uniqueness. It would also be useful in other, less drastic applications like reference designators.
