I (and I am sure everyone else) really appreciate all the time, research and effort you put into this plugin.
You are fortunate that none of your libraries have not moved to this horrific design.
And not to contradict you but I don't consider the appearance as one step forward. The "book" images are larger and while that is great for my older eyes, now instead of eight "books" being on the screen at one time, now there are only four.
