Feedback for 3 column dashboard

Ok so I have a couple of questions for those using the dashboard so some feedback would be nice..

  1. Do you want your users to have control over any settings on the dashboard? and if so, what do you want them to control?
  2. Do you want external site links to go to a warning page before leaving the site? And do you want your users to be able to turn this off?
  3. Do you want a nofollow attribute applied to links posted in the river?
