Hi Philipp,
If the only reason for a simplest version is the price, then take note that the price wasn't changed since the first version. All the new functionality is being added, every new release, without additional cost to the end-user.
Just the functionality related to the handling of metadata is already quite complex (create and import custom properties, properties remapping, metadata capture with OCR functionality, etc.) and so I have my doubts if assembling a new tool, that would include all of it, is worth the effort.
