Annotated links are a feature I recently added to ZTL. Though a small addition, it already made my note writing much more satisfying. Similar to footnotes (appended to an excerpt), they are attached to an outgoing link. But better they can be collected at the referenced target and hence provides super useful context, when looking through incoming links or bibliography.

The well-known syntax for Markdown footnotes is [^1]: Footnote description. The lesser known syntax for defining links outside of text is

Newts are a fascinating species, alternating between 
[aquatic and terrestrial] habbits. <...>

[aquatic and terrestrial]: https://... "Also called
semiaquatic"

The reading flow for plain-text is much better, when moving all definitions to the end. This has two shortcomings though. First, the title quoted after the link has to be plaintext (no MD supported), and cannot be mutli-line. Second, transforming an inline link to an externally defined one, is quite involved.

For ZTL I recently added a feature, supported by <Tab> key. If the cursor stays in the span of a link or LinkFoot, then we toggle to the other when pressing <Tab>. When the current link is actually inline, it gets expanded into an annotated link.

To support multi-line annotation I extended the Markdown syntax such that the link definition can be followed by a blockquote to define the annotation content.

Perhaps best seen and understood from a simple example

That is all, a quick and simple extension to taking notes. Allowing much better embroidery, also for the targets as we collected all annotations.
