This is a small upgrade that would make limewire easier to search for the files you want. When you search for something, there should be a "do not display" bar. The purpose of this bar would be to type in artists/files you don't want to see in your search.
An example of why this would be useful follows: Suppose you wish to look the artist Cham. You type Cham in on the artist search. You wait patiently for the search to load, and to your dismay 9/10 of the searches are about a guy called Chamillionare. The 1/10 of the searches that actully do have the artist are all the same song featuring two artists. If a "do not display" bar was installed, this problem could be fixed and make limewire easier to use, thus making it cooler.
