Indeed, that's because I haven't implemented it yet as I was still thinking of how best to do it. Probably just add all 'allocated to' for all open tasklists and let the use figure out what person applies to what tasklist...
BTW. Loving the new features in 6.7Dev1. I know it is naughty, but I am using it for some real work... Appears to be totally stable and the regular features all seem to work. Incredible.
I am backing up more frequently though...
Ha!!! So I found out a few hours ago. No harm done though.
Apart from that, I had it running for about 4 days, worked on it for about 15 hours total, had about 4 tasklists open, added up to 500 tasks (rejig to my year plan), applied a few filters, etc, etc, and it didn't miss a beat. It crashed when I was showing someone the task shortcut feature. Haven't tried to reproduce.
The only minor annoyance was the bug I have mentioned a few times, where the start and due dates don't show in the grid for a new task created from the completion of a recurring task (but do show in the edit bar).
