Also, "prettier" is in the eye of the beholder. I hate
hate HATE bookshelf metaphor UIs (yes, iBooks, I'm looking at you
). Yes, Alfa has a list view and I've not actually tried it so maybe it's half decent, but that bookshelf metaphor ... ugh.
Sorry, but if calibre ever adds a stupid "wooden bookshelf of cover pictures" metaphor, I'm going to have to fork the code.
