I love using graph view to traverse related topics, quickly, but I find it very difficult to find a specific note in the huge tree.
I’m often working on a note, or have several recent ones in the left sidebar that I need to find quickly in the graph view.
My suggestion is when hovering over a note in the left sidebar, highlight the node in the graph view. This would allow us to find and traverse quickly in graph view!
I think this request is actually different: the one you linked to seems to talk about a “selected note”, which I interpret to mean a note that is currently opened.
However, this feature request is about to highlight a note that is not necessarily open in Obsidian, but that is hovered with the mouse cursor in the side menu. That would be a quick way to go through notes listed in the menu and see where each of them are located in the graph. I’d love this kind of feature. 
Thanks for the correction @Jare I’ve withdrawn my previous post. 
Hello! Did you built that feature in the latest update1.0.0 ?? It would be so GOOD TO HAVE!
This seems like such a no-brainer… It’s really, really hard to find the note you’re currently looking at in the graph view.
Can this please be implemented? There’s no real point of looking at a graph view if you can’t find what you’re looking for in it.
