Hi

This patch adds buttons for every tag in show mode which means that
tabbing down to an attachment (or other button) is rather slower. As
someone who is not going to use the tag buttons (at least not very
often) Is it possible to avoid this? perhaps by making the button
optional or making the button only mouse clickable? (Since the buttons
in the headerline are not tabbable to then the latter might be
reasonable.)

Best wishes

Mark
