If you really want to step it up - support putting multiple book pages on bigger sheets, so I can print book pages on big double sided sheets, and when cut out, the pages will be in right order and orientation. A common prepress need, but relevant for own book page printing as well.
"....2020 goes by and i cant make a custom sized pdf book on lightroom? ...what is the book module for? is it just to keep blurb expensive and old as #%& printing services alive?
....and for this reason all of the book module is basically worthing ZERO (to me)!?
i will have to forget all about virtual copies and albuns and export everything to use another software ? all because i cant configure a 30 by 40 pdf page (on lightroom)?????
will these be possible this week ? i need to make a 30 by 40 (cm :)) book (pdf)!
come on ..... please !"
please add in the LightRoom LRC book module a way to freely custom the size of your books. Now you are forced to only use blurb sizes?
