Smart jfm Links is a free Chrome extension developed by runol. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This extension aims to assist moderators of jfmlinks.dk, a website, by automatically formatting text in the WYSIWYG editor on the page.

Upon installation, Smart jfm Links adds a button to the browser's toolbar. When clicked, this button inserts a WYSIWYG editor button on the page, but only if the page contains an editor with the selector "div.ql-editor."

This extension offers three types of automatic editor formatting. Firstly, it converts headings (H1, H2, H3, and H4) to bold text by replacing heading elements with elements containing the same text. Secondly, it adds a "Sponsored text" paragraph to the beginning and end of the editor. Finally, it removes empty H1, H2, H3, H4, and paragraph elements.

The inserted button can be clicked again to revert the changes made by the extension.
