You are right Tom.
Fabulous improvement.
However, one word of warning.
If you intend to re-organise everything into categories and as part of your housekeeping you decide to rename any of your BOs take special care.
Not EVERYTHING that references the BO in the BSV gets automatically updated.
For example....
-Referenced attribute for Icon Rules
-Queries that reference the BO inside Sub Reports
No huge drama but I would recommend changing only a single BO name at a time and testing so as to save you a big headache.
