Okular's "open recent" sub-menu lets you open recently-used documents.  However, that document replace the current document.  This is very inconvenient, since it means you can only open one document at a time this way.  

It also is, in my experience, non-standard.  Usually opening a recent document seems to open a new window for the document rather than replacing the current view.

At the very least please make this an option.
