I agree the lack of more distinct display if bullet items will take some getting used to...I have another teeny thing I see that maybe someday, eventually, sometime, in some near or far future time could be considered worthy of firmware revision...being able to turn off the underline of hyperlinks, instead just let the user set the behavior and color of links in a document.
Just a thought as while I am sure it is livable, the underlined links like that are, well, kinda fugly...
BTW, I get it that these things are often not trivial in the reader world...having tried to edit and clean up a few books over the past few years, I see how poorly formed books are in their native formats. So, I can see it being one of those coding choices where real value/benefit vs. finite developer resources. Not a but deal I think once I viewed a few of these test images.
