I finally ran into this as well when we started using the system for project management.
For us, the ideal situation would be a way to integrate it with the Google Drive Pack.
Features we need:
- Arbitrary attaching of files to Sections
- Attaching files to rows
- Ideally, if integrated with the Google Drive pack, for a specific column on a specific table the ability to specify a target folder and have any attachments immediately uploaded there.
