Currently the dicom tags of a node can only be seen in the developer mode of the property view. That is less than optimal.

A better way would be to display information either in a dedicated view/widget or as an overlay within the multiwidget (either one or each renderwindow).

There should additionally be a preference page where it is possible to select which tags should be shown (as not to drown the user in information), as well as some sensible default settings.
