Okular is the new PDF reader for KDE 4. It is also capable of displaying DjVu and CHM files.
One anomaly is that there is no option to clear the list of recently opened documents from the menu. Even clearing the most recently used list from the KDE 4 Menu does not clear the list within Okular.
It comes down to having to manually edit a file. The file in question can be found in your home directory.
Using my PC as an example, the file can be found at;
/home/Richard/.kde/share/config/okularrc
Close Okular first. Edit this file and delete the lines under [Recent Files]. Save the file, then restart Okular.
If anyone knows an easier way to achieve this, please let me know!
