Perspective Dashboard Component

I’m still tinkering with the dashboard component. I would like to be able to prevent the user from doing the following two things, but I don’t see a way around it. Any ideas?

  1. Closing a widget using the ‘X’ that shows up in the upper right hand corner.
  2. Resizing a widget. I want them to stay a static size, but it defaults to showing little re-sizing handles.
