If you’ve ever wanted to draw on an image or add a caption or text to your image then this is the plugin for you. Best of all it allows you to add your caption, save it, display it, then go back and edit it in different layers and objects laid on top of your image.
It extracts the text from the annotations and displays them as selectable and stylable text just below.
You can hold shift as you draw rectangles to make them perfect squares, same with the ellipse tool and circles.

The My Marginalia plugin for WordPress lets you format content with notes or comments aligned float:left or float:right to the main body of your content.
marginalia (n): notes in the margin of a book, manuscript, or letter

The plugin’s original use case was to present the show notes for a webcast with timestamps linked to the specific portion of the video being discussed. Similar uses might include providing commentary to accompany a transcript (noting all the lies in a politician’s speech, perhaps?).
This plugin takes advantage of the Gutenberg editor that became the new standard with the release of WordPress 5.0. The “notes” field shows in the editor as a RichText component with standard formatting controls, including the ability to add links. The main content (the subject of the marginalia commentary) can include multiple blocks such as paragraphs, headings, images, and other media.
