The document viewing area in OpenEMR 4.0 is much smaller than it was in OpenEMR 3.0.1. It would be nice to have the size of the document viewing area in OpenEMR 4.0 the same as it was in OpenEMR 3.0.1. We are in the process of upgrading from OpenEMR 3.0.1. It's really a nice feature to be able to view a PDF document within OpenEMR. With the decreased viewing area in OpenEMR 4.0, to truly view a PDF document I need to open it (not download) with my PDF viewer (Preview on OSX and Okular on Linux).
