Definitely support this one, I often find myself wanting to link something in the note just for the comfort of moving around the notes, but I DON’T want to ruin my graph clarity with kinda unnecessary/redundant link that clutter the view.
URL workaround is ok, but as stated earlier, it becomes unreadable quite fast. I also found out that if you have the Admonition plugin and for example use a normal [[bracket]] link inside a collapsible note, it does not create a link on the graph view. It’s another workaround, obviously creating collapsible note just for one link is ridiculous, but may sometimes be useful.
Eventually I think there were some ideas about “Tiers” or different levels of links shown on the graph, this would somehow resolve the problem if you could filter “level 2” (less important) connections from the graph.
Found these two, but there are probably more similar ideas:
Add Link Weights between linked notes : Graph View
Add support for link types
