The service account addition is an absolute Godsend. Many is the time I have had to manually go through multiple pages to exclude accounts from importing due to the clunkiness of the service user function. That's excellent. Thank you, that's a change request I'll be raising in the morning.
Under Sites/Users listing it would be nice to Show/Hide Service users as well as have a column showing if a user is one also. Hard to tell if they are or not without 10 clicks into the user.
