Just a single hint that the defaults have to be checked and should be thought about. As an inexperienced user, I trusted the default settings for too long.
In my case (to many overdue cards), the maximum reviews per day should have been increased (maybe the ease factor lowered too), but that’s not the point. The point is not to blindly trust Anki’s default settings, as many advisers recommend. It didn’t even occur to me that the algorithm could do nonsense with the default values.
That’s why I suggest introducing a hint (just that the defaults have to be checked, not a solution) after a certain time.
