Thanks for awesome program. But 0.13 have regression to 0.12. For pdf that you can find in attachment, if we excluded from merging pages № 1-2;27;158-164;208-215; than BRISS 0.13 freeze and the end of creating merged previews (see screenshot in attachment). In 0.12 this process is normal, and with it I can crop this pdf, but 0.12 is not good in usability then 0.13.
Also will be good, that in future we have able to manually merge exludings. For example in this book pages from 158-164 and 208-215 have same crop filed sizes, but I must manually edit every page from this range, but I think option that merge this range into one will be good.
