I posted a similar request.
Since the backlink panel shows the part of the line, couldn’t it just show the entire line? Is it mainly a UI thing to display it?
I think showing more than that line (nested bullets) could get unruly in backlinks panel & let alone it being possible. (Roam handles it nice enough, but it’s an outliner afterall)
I’ve personally been playing with using hidden UIDs at the end of every line I write, to bring some of that more granular outliner/Zettelkasten note/thought identification. But it’s not really functional right now. Just an experiment.
Hoping eventually a plugin could embed a line by finding a hidden UID and then just hiding the UID from the render when it embeds, leaving just the text.
