Biggest opportunity: Swap “math” for “equation”. “math” isn't earning its slot: you're not in the first 24 results for its own search. “equation” sits at #5 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 2K of 43.3K 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.

    Thanks to Tom for reopening this plugin for updates. It must have been a chore to satisfy the “administrators” but the result is great. I have been using KaTeX all the time. WordPress complained about lack of updates where there was no real reason other than administrative. I am sure also in the future, updating only means adapting to new rules. Ger

    Is it possible to render KaTeX for inline mode in a paragraph (Gutenberg preview)? Please consider this in next update. This topic was modified 2 years, 4 months ago by Difa. This topic was modified 2 years, 3 months ago by Difa.

    This is a great plugin for everyone who wants to use the power of LaTeX or KaTeX to display properly typeset math on their site. My favourite aspect of this plugin is how the Ka block displays a preview of the formatted text. While you can insert KaTeX statements using the shortcode block, if you do that, then the equations will be left justified, and there is little to do about it. Using the KaTeX block, the calculations will be properly centred between the margins set by your theme. Great job by the developer! I hope that the plugin will continue to be maintained so that we don’t lose compatibility with the latest versions of WordPress, as there are very few options otherwise.

    Veny nice plugin. Able to use very easily and without any issues. A cakewalk if you know latex syntax. Rendering is very fast too. There is lot of accounting related math content on my site (eduxir.com) which requires to use math equations. Was able to achieve very easily. One request to the author is that the font and related files are downloaded even on the pages that do not use katex. We need to modify the plugin to disable this option. If a configuration option that could be provided which would retain the configuration even after updating the file, would be of great help.
