Feature request: preview internal link in pop-up

First, sorry, I'm not sure where I should put feature requests, so I'm trying both here and there.

I recently saw that evince added a feature to display the internal links in a pop-up like display:

It is just super useful, especially when reading science papers: that way, you can view, without moving to the actual part in the PDF:

• the definitions introduced before by just moving your mouse on "See Def. 2",
• the equation by just moving your mouse on "Eq. 5",
• the precise references to other papers by moving your mouse on "[1]",
• the footnote by moving your mouse on "myfootnote²",
• ...

Of course, you can always click, but then it's harder and longer to move back to the position you were before in your file.

Would it be possible to add this wonderful feature to Okular?

Thanks a lot for considering this feature request!
