There have been many threads complaining about how hard it is to distinguish hyperlinks from surrounding text because the dark blue color doesn't look much different from black text. Here are a few of them:

EDIT: Here's a screenshot from a PB I created which demonstrates the problem more graphically:

I am asking for one or more of the following solutions, in order of importance:
(1) Brighten the color of blue that you use for hyperlinks -- please do this at the very least, and do it soon; it's a matter of accessibility for people with not great eyesight
(2) Add a UI for user to be able to choose how they want hyperlinks to be displayed (color; underline, bold, italics); - if you do this (which I hope you do), #1 is not strictly necessary, but I realize that #2 would be harder and take longer, so do #1 soon as a stop-gap measure. The current situation is untenable for many of us.
(3) For PB's, pick up other formatting (underline, bold, italics) from how the link text was formatted in the .docx file so the PB creator can at least make their links stand out more than the normal Logos ones do.
