It would be nice if "per" or "pow" would sort duration by remaining time on spell cast by user then extra-user spells listed last. Best case if extra-user would sort duration by remaining time affected.
Is this, by any chance, a scripting-related request? I ask because there are ways around needing this with any of the major scripting clients, and I can't imagine being able to do anything complicated enough for it to matter with Stormfront. And, for non-script stuff, it doesn't seem like it would make much difference. If it's script related, I'd be happy to go into more detail for you.
