Allow the use of a context menu command "Hide these results" after the selection of results in the Wishlist (and/or Search) windows. I don't know how practical it would be to implement this - if uniquely identifying said files and filtering them would be resource-heavy or generate large files when hiding a large number of results. Preferrably with the ability to Undo the last change(s) for those cases when the user operates their client in error/stupidity/nontypical mental state.
I request this as oftentimes I use the Wishlist for very obscure releases, sometimes with search strings that return huge lists of unrelated popular artists. Searching through the same long lists of garbage I don't care about over and over, hoping to find one user sharing what I want is a huge chore. Othertimes, I'll find what I'm looking for, but in a format or bitrate I'm unhappy with, and I'd like to continue searching for a better copy without having the existing files I've already grabbed constantly popping up in my wishlist results. I might actually start paying attention to my Wishlist results again if I didn't have to wade through 40+ windows confirming none of it was anything I wanted/didn't already have.
