Modify my content

hello everyone,
I don’t know whether this request has already been included in the requests for a future version.
But wouldn’t it be nice to be able to edit ‘contents’ directly from the GUI? With some pdf readers I used to be able to do this, why is it still not possible with Okular? This way you can create indexes of your books.
Thank you

If you want to manage a library of PDF books then Calibre is the best.

But I assume you mean to edit individual PDF’s?

Yes, but I just got an answer about another PDF Viewer that does what I meant: masterpdfeditor

But I still think that having these option on okular cool be very nice
