Note that there are three tag modes: full, partial, and none.
I have always thought that full should be full--all tags are
shown in full; none should be none--no tags; and partial should
be set up to show your preferred view for each tag, and partial
should be made the default view. You can set things up this
way yourself via the dcf file.
So you could set up your dcf file so that para show as icons
in partial mode only, and set up other tag preferences for
partial mode, and set full mode to show everything. With
partial set to be the initial view, the users will get the
same view by default as before, but they can easily toggle
to full (or none) tag view to see things like attributes.
(It is also the case that one should be able to see a tag's
attributes as a tool tip if you hover over the start tag
with the mouse long enough.)
