I've only been beta testing for a few days, so please excuse me if I've missed posts about this (I have searched) or if the feature works differently from how I think it does in Logos 4. The parallel passages and harmonies add-in in version 3 is quite powerful, and something I use frequently. I especially appreciate that it sets the full texts in columns, like the print versions typically do, but in the Bible version I choose. I also like the ability to select the sources (Aland, etc.) for the parallels. So far I've been able to use the parallel passages of the passage guide to get a columned list, verse by verse, of the references (not columns of text), which I find of limited usefulness. Sorry if I'm missing something obvious.
