XnView Software

Yea, I Know that even at 100q some quality is lost, It's just that I was testing various batch-converting softwares, all of then let you set the quality at 100q. I find out that most of these software use the same jpeg encoder (at same parameters, they output the same pixel by pixel jpeg), except Xn...

Just wondering, why I cant set the jpeg quality to 100?, 99 is the maximum t_t

Man, MP is portable, it comes in a zip file, it saves the conf files in User\Program data\XnViewMP, but there is an option to save it in the program folder
Tools > Settings > Integration > Save settings

I have a related problem. When I drag the images to another folder (normal windows behavior) the program only makes copies in the other directory, instead of moving them.
Also, it would be good to have an animation (a shadow) to know that you are moving a group of pics
