@redeagle Yes that's exactly what I was talking about, standard is free, but often Adobe uses a lot of proprietary features, and their grip on business community forces businesses and governments to use those proprietary features, so which means any editor is not going to be that useful, since majority of interactions going to be on business related side.
@archit3ct Fortunately, it's not majorly different. Adobe won't let you off by business means. The PDF format is an open standard.
