Dear all

I have been using Ubuntu for a while now (4 years), but I am still a begginner-google-dependant user.
I dont know much about Linux, or programming, but something intrigues me.

How come after all these years developing PDF readers for linux there is still no native PDF highlighting??? Is it so difficult to achieve?

Im getting tired of using windows softwares under Wine.

Okular and Xournal are not options, you cannot save the annotations to the PDF files and if you do, other PDF readers do not recognize it.

Could somone explain me why there is still no native PDF reader with Highlight in Linux???
