Version 1 of #4827

Reiterating/refining #3904: I think the yellow "Criticism of" bubbles can and should be replaced by a graphical indication that is much easier on the eyes. The dropdown line can be made red if the comment it leads to is a criticism, and the bubble on the criticism can be eliminated. Reading the yellow bubble to get the idea # it is referring to, then searching the ideas above for the matching # is inelegant (even if it is usually the one right above).
