I made rendering packages for clients that look a lot like this. When I staple the views into a PDF there's some manual work that could be automated. Currently I'm spending a lot of time re-ordering images doing extra clicking.
See my proposed mock up below that I think would be beneficial.
1. Allow the user to save multiple views to a single view set for later use.
2. Allow the user to run design options variations in a single batch render operation.
3. Allow PDFs to be automatically collated per their filenaming mode (assuming that their PDF stapler uses alphanumeric ordering). This can be tedious if there's a lot of similar images that need to be manually re-sorted.
