Hi Deborah,
Project name I can help you with, add a column to your proof approval report, switch to text mode and enter the following:
displayname=Project
linkedname=document
namekey=view.relatedcolumn
namekeyargkey.0=documentVersion
namekeyargkey.1=document
namekeyargkey.2=project
namekeyargkey.3=name
querysort=documentVersion:document:project:name
textmode=true
valuefield=documentVersion:document:project:name
valueformat=HTML
Pulling in a thumbnail is a bit more problematic in a proof approval report. The following text mode will work for some document formats, but not all (PDF's aren't supported for example):
displayname=Thumbnail
image.valuefield=documentVersion:document:previewURL
textmode=true
type=image
valuefield=documentVersion:document:previewURL
valueformat=HTML
If thumbnails are imperative, I recommend exploring a Document Version report instead of a proof approval report. Thumbnails can be easily added to document version reports, and they can mostly replicate proof approval reports if you get the filters right.
Best Regards,
Rich.
