My preference of Okular over Adobe Reader DC is it has less functions but several useful ones. Particualrly annotations (can change properies including highlight, underline etc).I do not use bookmark largely because individual file book mark location is cumbersome (it shows book marks of all the files?). Besides copying option both text & image.

However recently update Okular (window 11) removes THIS highlight property. A fall back on older version inevitable. May be if this disabled search for a substitue for Okular. Hope they restore older version on winodows.

I use Okular and for the most part it performs well with PDFs. The main advantage in its support for PDFs is that it allows you to print pages from a PDF with PDF as output. So you can print pages from a magazine PDF which might be 25MB in size to a smaller PDF that might be 1MB in side.

Where the problem comes is epub files. A certain percentage of epub files will not open at all or open VERY slowly. Also, a number of epub files will open and then show essentially blacked out pages. I’m not sure whether this is the fault of Okular or badly formed epub files, but it is very annoying. Only Calibre can open epub files with pretty much no problem unless the file is corrupted in some way.

Also, Okular has not been updated in years and is apparently an orphaned project. Would be nice if someone took up the mantle.

Okular is one of the best kept secrets. KDE applications are always pretty impressive and Okular is no exception. I like that it is able to open just about any document format there is. It also has features not found in other document viewers. I have used Okular as my go-to PDF viewer since I made the switch and never needed to change. Bookworm is another great application I now use thanks to your informative articles. Its management capabilities make it a must have.

I recently stumbled upon a very cool mind-mapping utility from KDE called Semantik. It is one of the best open-source applications of its kind and I am surprised it is not more well known. Maybe you could check into it and inform the masses. Thanks again for your great work.
