Aptly, /t/ideasforsnapzu is a perfect example of a tribe that needs a dedicated search facility. For instance (now this could get confusing, but that's kind of how I like it) - if you wanted to find my existing post on ideasforsnapzu about how we need a "search snaps in this tribe only" facility, you have to do a general search which does not return my existing contribution on the first page (maybe the search algo needs to be improved too for synnonyms and the like). This is leading to many people posting the same idea rather than just voting up existing ones, somewhat breaking the function of the tribe in general. I'd say this isn't just a nice idea, but an absolutely essential feature that should be right at the top of the priority list.
