There should be a spot on the Job Details page for certain documents to be placed. There should only be allowed one document at a time in this spot, and the document history should be accessible.

For example, a link to the Site Plan document should be prominent on the Job Details page. Just as the Contract and revision history is shown on the Job Details page. Our Site Plan will show roof access points, scope of work notes, issue areas, special notes from customer such as do not drive on this driveway, solar panel removal, o'hagin installation, etc.

These document links should be customizable so we can have as few or as many pertinent docs as we desire. They should be accessible from the sidebar.
