Side Matter

by setzer · Uncategorized

Turns footnotes into sidenotes, magically aligning each note in the sidebar next to its corresponding reference in the text.

Try it live opens a temporary test site in your browser, which can take about 20 seconds to load. Plugins that rely on outside services or a full server may not work completely there.

Biggest opportunity: Swap “academic” for “sidenotes”. “academic” isn't earning its slot: you're not in the first 24 results for its own search. “sidenotes” sits at #7 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active

At least 100 of 9.5K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,764 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 12+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 3.7.41, well behind 6.8.

    For my site, I’ve been waiting for annotations as marginalia (sidenotes) for a long time and I am so grateful to the developers for coding this up and sharing this WordPress plug-in within WordPress’s open-source add-on ecosystem. The only addition I’d request or hope for is support for multiple annotations (for example, two or more separate sets of annotation in the same documents). I have posts in multiple languages with two separate sets of annotation and right now I’m using this plugin and the Annie plugin to support both (one as marginalia, the other as footnotes).

    I like this to be honest but not sure how to use it if no sidebar is present! XD

    So far as I am aware, there’s no other plugin around that can do what this one does — and it does it perfectly! The developer provides really fast and helpful support too!

    I’m converting a collection of academic texts into a WordPress site, and this plugin is precisely what I needed. Excellent work.

    Does this work with the popular 2012 theme? I am using that theme and it doesn’t seem to work. Does the post format have to be full width?

    I love this plugin! It works perfect and it’s great for people who love footnotes but want another solution for WordPress. Thank you!
