Thanks for your input @asakka.
With DOpus 12.7.3 we now have relative columns, without the need to pre-scan the folders. I have also looked at the multiple column calculations issue your raised. Let me know what you think.
Updated to version 1.8
- Added support for new columns in 12.7.3 graphrel, igraphrel and percentrel.
- Updated code to prevent calculation of columns that are not visible (as discussed here Custom columns reduce muliple processing)
