Allright I understand now ! Thanks for the explanation ! You're right in fact there is just another Open Manager, like Flex Manager was made from Open Manager too.
I'll see the staff to make changes on the new ! I agree it must annonce that's it another Open Manager skin, based on the Flex Manager skin, with a new install folder ! I thinks it's just a mistake ! Bad words were used ! Sorry for that.
EDIT : The covers resolution seems to be 348x400.
