I use Aria Citrus on my board and it is generally very well received by my users. However, the icons that appear on the left side of the forum threads are not very expressive:

They are very small and it is difficult to differentiate between them, even though they are explained at the bottom of the page. I have noticed it myself and some of my users have brought it up. I have noticed that I don't really look at them anymore. Instead I look if a thread title is in bold to see if it has new posts.

Would it be possible to make some improvements so that these icons regain their usefulness? What do the other users of Aria think?
