I have just started working with Ubuntu.
My work includes a lot of books that to be read. Hence while reading, I need to --comment & highlight
the characters in the form of PDF & DJVU file.
I have installed Document Viewer
and qpdfviewer
. But both of these softwares do not have this option.
I can't find any other in Ubuntu software updater
. So Please suggest me some softwares according to my needs.
