Logos for Mac has made huge strides. I have put it through the paces this weekend and can see the day coming when I will unplug my virtual machine for the last time!
Anyhow, I suggest that there be a bit more white space in between search results in the book view and maybe tweak the fonts a bit. Without such, the text runs on and is hard on the eyes. I have put the results from the Windows version to compare how much more readable it is.
