feature enhancement request: I use the right click function a lot in the 'icons only taskbar', the default taskbar/dock of KDE, for Libreoffice writer and for Okular, to select recently opened documents. The number of recent documents is always 5. I'd love to be able to expand this to a larger number, like 20. 
So this is a request for an option to be able to set the number of recent documents that are shown upon right clicking the launcher of libreoffice apps or okular etc
