Okular supports opening multiple files at the same time on the command line by specifying multiple PDF files as arguments. However, if one wants to open multiple PDFs within the Okular QT GUI, one must open each one one at a time through the Open dialog since it is a single-file open dialog.
I suggest this Open dialog be changed to support multiple files so that users can quickly open a set of PDFs in a directory without having to run okular from the terminal.
Interesting. The code actually loops over all selected files, but the dialog is not executed in a mode where multiple files are allowed. This might just be a porting regression, and should be easy to fix.
It is easy to fix:
