How was there no sort by subject field?
Sitaram Chamarty - "Really, at the risk of repeating myself, LN didn't have "sort by subject line" till about 2004 or so -- now come on that's a deep scar, admit it."
It has been a number of years since I've used Notes in a work environment but you could have a view in Notes that was sorted by column on any field in any form. Notes allows you to create any types of view you want and to sort sort accordingly. Is it the fact that it wasn't default view is the problem?
