Comments about Okular as an Alternative to PDF-XChange Viewer
It showed the text in the forms; something the other alternatives didn't. Easy to install and use through Antergos.

Most users think Okular is a great PDF-XChange Viewer alternative.
- Okular is Free and Open Source
- Okular is Privacy focused














































Now okular saves the annotations metadata to the pdf itself as far as i know.. so all is great now about okular :)
