Within the Document Viewer Pane, it would be nice to have a few additional tools rather than just the comment feature. 1) Standard set of tickmarks and letter connectors. 2) A calculator tape so if they are adjustments made after the original PDF Document was received, one could add those calculations to the existing file. Similar to the Adobe PDF Flyer calculator. (For example, you have a bank rec and then a client makes a reconciling adjustment after the factor and submits the journal entry to you. It would be nice if I could within the existing bank rec PDF use a calculator to take the unadjusted book balance + JE posted = reconciled book balance and paste it to that bank rec.
