You are right. There is index_sort which I do not personally need, but some users want and now it has been added to Roundcube - great.
However I have one mailbox which is very large and Roundcube takes a long time to sort the messages in it (threaded or not). For this mailbox I want to just see messages in the order the server sends them back, and not have Roundcube sort them at all because it is too slow.
Without threading if you use index_sort=true and sort_col=date, then you'll get what you want.
