I ended up getting the newest version (5.24) because that's what was on the website (previously used an older version because I couldn't be bother to update it). That is, until recently, when I got a new laptop and had to reinstall all of my programs. Sure I don't have access to any of the cool premium features like creating folders to better organize my collection, but it does it's job and I've been happy with it.

it provides a good managing system for me to favorite books, easily search for the one I'm looking to read, it remembers the previous books I have recently opened and where I left off, and lets me read books in a smaller window (for multi-tasking purposes). It can handle my large library of ebooks (900+ files) without being too slow. I've been using the free version of Icecream Ebook Reader for a few years now because I happen to like the program for a multitude of reasons.

Tl dr icecream ebook reader has these terrible popups that interrupt your book every few pages and won't let you continue reading for 10 seconds, and i want to disable it because i swear there was a version that exists that didn't do this
