So far it has been functioning great.
Cosmetically I have two things left. I would like the ability (if possible) to hide the grey/white line down the left side, maybe coloring it black would hide it. And the second you are already working toward, it would be great if on large covers the grid can show 3 covers across. Although 2 covers per shelf is growing on me.
This version change looks to be shaping up as an outstanding step forward. Now if only I could give the app a higher rating...
