It would be great to be able to lock the elements in the desktop version so that when using the scroll bars (on a slicer) that the control does not lift off the page and be dragged after I have found...
Also Kim, it would be great if as part of the lock, we could get rid of the component outlines so that mousing over your dashboard didn't highlight them. i.e. put the report into read-only mode (less filters).
