Can we have a snapshot feature like Skim in MacOS

Is your feature request related to a problem? Please describe.
When reading long papers with references (hyperlinks) like eq. 3.15 or fig. 20 which refers to something pages away from where it's cited, I have to keep going back and forth to keep track of them.

Describe the solution you'd like
I would like to have a snapshot window of the reference displayed when I select or my cursor suspend on the hyperlink. This is a similar feature to the PDF reader Skim in MacOS.
