SuperLight CPT Manager is a minimalist WordPress plugin that lets administrators create Custom Post Types without clutter or bloat.
Each CPT automatically:
<ul>
<li>Registers itself with WordPress</li>
<li>Supports basic post features (title, editor, thumbnail, excerpt)</li>
<li>Appears in the REST API and block editor</li>
<li>Comes with a unique shortcode (e.g. <code>[superlight_cpt slug="book"]</code>)</li>
</ul>
There are no extra scripts, no custom tables, and no unnecessary settings — just pure, clean functionality.
Features
<ul>
<li>Add, edit, import/export, or delete custom post types on the fly</li>
<li>Each post type gets its own shortcode</li>
<li>Works with Query Loop and block editors (<code>show_in_rest</code> enabled)</li>
<li>All CPTs stored in a single WordPress option (<code>superlight_cpts</code>)</li>
<li>Adds lightweight admin hooks for companion plugins, including SuperLight Taxonomies</li>
<li>No dependencies, no setup, no nonsense</li>
</ul>

This is a WordPressified version of the excellent, lightweight (for real!) imageLightbox.js (MIT-licensed) by Osvaldas Valutis (http://osvaldas.info/image-lightbox-responsive-touch-friendly)
This is his introduction to the lightbox: 
“As for the image lightboxes, I have always lacked simplicity for them. I mean not only the visual design, but the overall experience: from implementation to UX. All due respect, but I have never liked any of these light-fancy-face-boxes. They all were solving problems that just don’t exist: lots of unwanted features by default, total mess in markup, no native behavior for touch screens. I was working on a project and needed an image lightbox that solves these problems. I needed a lightbox only for images, not video, text, and iframes at once. I made ImageLightbox.js.”
This version autodetects all links to image files and opens them in the lightbox.
For your “install, activate and go”-convenience, this plugin comes with a minimal CSS that easily can be deactivated and/or replaced.
The plugin can also be themed to your liking. An example theme is available here: https://github.com/bjornjohansen/imagelightbox-theme-smooth
