You can make a formal suggestion by dropping it in as an e-mail
However I can forsee a problem - although you had added a comment to the fault, a member of support wouldn't automatically know that you had put a comment on the fault. I guess it could put an e-mail in the support box to alert them - maybe the sum total would be slightly more user friendly than just dropping them a standard e-mail with your comment/update.
Anyway if you send it in as an e-mail (just address it to support@zen.co.uk ) I'm sure it will get considered, and if its decided it will be of enough benefit, then duely implemented.
Thanks for the feedback!
Kindest regards,
