Color Contrast Testing
The color contrast testing tool is a reduced-feature implementation of my own color contrast testing tool. Use it to test any pair of colors you’re considering using together. If you’re looking to test the color contrast of your site’s front-end design, a tool like WebAIM’s WAVE toolbar is going to be more effective.
Disable fullscreen editor by default
Since WordPress 5.4, the block editor has opened to the fullscreen mode by default. Since this information is stored only as a local setting, this will happen for users every time they open the editor on a device where they haven’t previously configured their preferences, if they reset their local storage, or when setting up a new site.
Enabling this feature in WP Accessibility still allows you to choose full screen editing as your preference, but it will not be the default.
Since WordPress 6.1, block editor settings such as dismissing the welcome modal, disabling fullscreen mode, and other equivalent settings are saved in user metadata, and are no longer dependent on local storage.
Search alt attributes
By default, WordPress media library searches the title, description, and file name. The
alt text of a file is not part of the search query, though it can be very useful information when your library includes significant descriptive information about your images in that field.
This is an open issue in WordPress core, but is currently blocked by performance issues. Those issues are still valid if you’re using WP Accessibility to enable searching by alt text, so if you find that media library searching is too slow, you may wish to turn this feature off.
