Well I'd love to be able to package all PDFs to a folder, or all eps, or all tifs or something. I've needed that before. But it's just a matter of separting the file types after packaging then relinking them in InDesign.
I've also always wanted to be able to package a book to different folders. I'd like the book to be packed with
Chapter 1
Links
Chapter2
Links
Chapter 3
Links
etc.
That would be great because then updating an image that's in Chapter 2 and 5, but only wanting to edit the Chapter 2 image or something, is somewhat of a hassle at the moment.
You might even want to send Chapter 1,2,4,5, 10 and 17 to someone else to work on. But you have to do all that separately by opening each file and the File>Package.
Would be neat to just select those chapters and choose Package to Individual folders and then each chapter name gets it's own folder.
Currently you can package selected documents for print, but all the indesign files go into one folder and all the links go into a single links folder.
That's always irked me, right back as far when I started with InDesign in CS2.
