Comment 1 for bug 328661

The mechanism for guiding Do's learning is simply using Do. If you think that it is not learning well enough, or fast enough, the solution is to improve Do's learning features, not to add additional mechanisms for the user to explicitly affect the learning system.

On the other hand, if we cannot sufficiently improve the implicit hints and Do's ability to learn user preferences without being told, *and* we are able to determine that the added complexity you suggest would result in positive net user benefit, then we could consider explicit learning hints.
