GRiker and kiwidude,
Create Catalog, Find Duplicates and Modify ePub are the only items I've added to the limited space on my default menu-bar.
As my ebook collection keeps growing, I'd be lost without them. I use them several times each week. They've saved me many hours of work by replacing the tedious manual methods I previously used.
Thanks from an old dude in Amarillo,
P.S. I just recently learned about Modify ePub, and I've become addicted. Very handy!
