when I create a task, I would love the ability to either move the activity stream below the post comments/comments or the ability to completely turn it off. It's extremely cluttered looking now, imo.
I love feng office other than a few points but nothing is perfect and of all the PM systems I've tried, this one is one of the best by far.
Another thing I would like to see is collapsing post comments within tasks. After lots of communication the page is getting really long, I dont' like that, it's in convenient. Rather a forum type discussion board associated with the task would actually be better overall.
Keep up the great work guys.
