Thanks for stepping forward to help, Jun. I know the "I'm busy" feeling very well, as that describes my situation, too.
It's great that so many of us are busy with paying jobs, OpenACS or not, but it does seem to hamper progress on important packages.
Why is sort order so important to ETP? Does it have weird hooks that depend on a particular ordering? Normally for the file folder paradigm to make sense to users it would seem sufficient to sort items alphabetically by name, something like that ...
