When you release a domain, the process is very straightforward until the final confirmation page. There are progress tabs on the right hand side of the screen and the confirmation page shows 'Finished' being highlighted which tells you that the process is complete, however, it does not show the name of the domain(s) that have been released. All previous pages show the domain in question. If you get interrupted or called away, given that the transfer process is not instant, it's easy to forget which domain has indeed been completed, so having it showing would be extremely helpful!
