We're loving the new support for Geospatially-enabled PDFs in FieldMaps.
However, I think it could be improved by adding support for multi-page pdfs. For example, if I export a map series and wanted to view it in Field Maps. Or if I had a document with the same general area at multiple scales.
We rely on similar capabilities in other applications currently, but we'd like to consolidate applications for our workflows. Adding in PDFs is a great start, but making multi-page support would be great.
