This is a year old, but I totally agree. To flesh this out a bit more, the Islandora Batch Derivative Trigger is a fantastic tool, but it seems to only work at a "shallow traversal" level. It can generate derivatives on direct children of a collection, but not children of those children. So in addition to newspaper issues, I'd love to see it work on compound objects and pages of books - and I'd love for this feature to be visible in the GUI.
Would this be difficult? Would others be interested? My organization would be willing to commit some funds to this project. It would take a lot of command line management off of my plate as the manager of an Islandora environment.
