In a number of places in Moodle (e.g., the "Database" feature) user actions sending data are followed by an interstitial page containing minimal content and a message like, "Your entry has been saved." These pages are set to redirect to another page, using JavaScript, after three seconds.

Why it matters

Three seconds isn't nearly enough time for a screen reader or magnification user to understand a page and read the content on it. Every user was initially confused by this feature, and eventually very frustrated.

Possible solution

Remove all interstitial pages. Confirm user actions with a message on the next page.
