Would very much appreciate capability to merge files taking pages alternately from each input file while also retaining bookmarks. I work across multiple languages and need to read them side by side, so rather than browsing two files, prefer to have them on the same file so that page turning is easier. PDFSam offers the alternate merging capability, which I use every day, but bookmarks are lost so that I need to keep referring back to the original files to locate content.
In addition, if pages from the two files can be automatically arranged on the same page (just like 2-in-1 printing) that would also be greatly appreciated. At least among conference interpreters, these features would be a killer feature. Please kindly consider.
