Feature Request: Support parsing link types from [[Note|Alias&Relation]] syntax

[HoBeom]

Thanks for your great work on this plugin! This feature would make Graph Link Types even more expressive and user-friendly in a graph knowledge workflow.

I’d like to request support for parsing edge types directly from the alias portion of Obsidian wiki links using a & delimiter syntax.

This allows users to semantically describe relationships inline, without requiring frontmatter or dataview fields.

✅ Supported Formats

Syntax	Display Text	Relation Type	Note File Target
[[Plato|Socrates&teacher_of]]	Socrates	teacher_of	Plato
[[Plato|&teacher_of]]	Plato	teacher_of	Plato
[[Plato|Socrates]]	Socrates	(none)	Plato
[[Plato]]	Plato	(none)	Plato

⚠️ [[Plato&teacher_of]] should not be parsed this way because & is valid in note titles.

Reference Implementation (Experimental)

I’ve extended the getMetadataKeyForLink() function to support this logic. Here’s the relevant snippet:

private getMetadataKeyForLink(sourceId: string, targetId: string): string | null {
...
for (const l of sourcePage.file?.outlinks ?? []) {
    if (l.path !== targetId) continue;
    const disp = (l.display ?? "").trim();
    if (!disp) return null;

    const ampPos = disp.indexOf("&");
    if (ampPos === -1) return null;

    const aliasPart = disp.substring(0, ampPos).trim();
    const propPart  = disp.substring(ampPos + 1).trim();
    if (!aliasPart || !propPart) return null;

    return propPart;
}
return null;}

This checks for outlinks with a display string of the form Alias&Relation, splits them, and uses the right-hand portion (Relation) as the edge label.

Additionally, I would like to have a function (or CSS snippet) that hides after the & delimiter in a link’s display text, so that only the part before & is visible in the rendered note. This would ensure a clean and intuitive display while preserving the semantic edge information for the graph.

Thanks!
