I decided to give okular
a try for editing pdf files but I am having an issue with the 'typewriter tool'.
The text I type does not appear on the pdf itself within the okular editor. If I save the file and open it with another program it appears normally though:
Changing the font type, size and color didn't change anything. I also can't find anyone else who's ever had this problem so I'm at a bit of a loss here.
