Pro Free and open source software

It isn't immediately obvious how to do this, but the instructions are here.
As of 13 June 2018, the icons/screenshots on that page look different than what can be seen under Evince v3.18.2, but the devs have been alerted to this discrepancy, and there are requests they make the finding/using of annotations more intuitive than they are now.

Click/tap the magnifying class in the top bar.
Pro Digital signatures
PDF Studio Viewer is the only free PDF viewer for Linux that recognized digital signatures from docusign in a way that lets you easily verify the signatures.
Pro Measurement tools
Pro Advanced print & search options
PDF Studio Pro is really an useful PDF editor. Earlier I was in MS Windows and was using Adobe Acrobat. But after switching to Linux, I was having problems with PDF editing. PDF Studio Pro has compensated the crisis. This is more like Adobe Acrobat earlier versions, in terms of look and feel. That’s user friendly. As I’m neither an expert nor a commercial/professional person, I always prefer user friendlyness. Command icons are clear with tooltip already written. Menu is elaborated well break-up. Very less searching for what I’m looking at. Also, all the functions seems to be available, so far I have tried.
