When will we have European (or custom) paper sizes in the BOOK Module? I am fully aware that Blurb only supports US paper sizes but there are many non-US printing services which will print a book from jpg or pdf files. You should be able to support sizes other than those used by Blurb. The recent improvements in LR 7.5 were great but I think will only be usable by American users. Come on Adobe you have MANY users who do not use US paper sizes!!!!!
