Hightlight link's destination in the link's preview popup
Hello. I’m sorry if there is a similar issue, but I couldn’t find any. Anyway, it would be nice if there was a way to highlight a link’s destination a little on the preview popup.
The problem is that it’s not instantly clear in the preview popup where exactly a link points to. I often read papers with 2-column layout where most of the links point to the “References” section which contains a lot of entries. Sometimes it takes me several seconds to find required entry in that list (and on which page's side it is). The second example shows a similar problem with footnotes. It’s a list of 9 elements and at the worst case I have to look through all of them, yet usually, when I’m looking at the preview, I want to quickly find the definition and go back.
I know that often PDF links do not contain precise destination (and it’s size), and when they do it’s usually somewhere above the actual place. Like in example 2 above the destination for “14” entry is actually between “12” and “14”. Plus, if we mark the destination directly, it may occlude the text.
So I sort of propose a solution (assuming we know at least the destination's "y" coordinate). We can just draw a small blue (yellow in night mode) half-transparent arrow at the preview’s edges. It’ll be on the left edge when the destination is somewhere on the left side of the page and on the right edge when the destination is on the right side. Here is some examples how it would look like.
