    88 == Add built-in attribute weighting support ==

    90 Traditionally learning algorithms do not support attribute weighting and treat all attributes as if they were equally important, but this is not the case in real data sets. It is known that variants of algorithms that use this additional data usually perform better. Because Orange at the moment does not include functionality for this kind of meta data, none of the algorithms support it out of the box. It would be great to add support for this (and possibly other) kind of meta data to attributes and other data structures and extend various learning algorithms to use it. For the second part some research of how to add this to each of the algorithm and probably how to generalize the solution will need to be done.
