Absolutely agree with that. For instance, through a setting could be used the first (or unique) alias to be shown at graph instead of UIDs And when alias is not present, then show UID (note name) as always.
BUT maybe using a Title field in YAML would add compatibility with Zettlr, for instance.
If I had to choose one, I would take Title method for compatibility aspects.
This is the only pending point that is stopping me to start dumping all my notes to Obsidian.
