Feature Request: Preview of Internal Links

May I suggest a new feature: preview of internal links (like in Skim pdf viewer): When the cursor is placed on a link, Skim shows its preview in a little pop-up window. I find it VERY useful when reading scientific papers.

Yes, this please !
Will be very helpful for many people.
For now, I can only do clicking the internal link and then press “alt + back” to go back.
