I am looking for a way to set a colored background for footnote numbers in text, or give them some other visible distinction, so that they are more easily noticed when I am scanning through text. I think that I did this in the past with visual filters, but I have not yet found anything in help or here on how to do this (at least, not in the searches that I did).
Maybe this was in version 3. I am not sure.
Any thoughts on how best to do this in Logos 4.
