Hands down the best comic book reader on all platforms. Blazing fast - easy to use - great options. If I had the chance to change something, that would be the ability to go to the next or previous image with a single button (eg PgUP and PgDn) instead of the combination keys command + [ or ]. Also it would be nice if it could be implemented in the images, the number of the page and the total number of images (eg 4/24).. And that is that!
I suggest it wholeheartedly to anyone reading comics or want to view pics / slideshow. Very stable app too!
