Nobody uses data quality. I'm convinced at least partially that's because you can only see it when you're looking at the release page... and by then, you can already basically see how good or bad it is. I really want a simple way to see what I have properly cleaned up and what I still need to fix when looking at a composer('s release list), and it seems like data quality would be a reasonable fit for this... if only I could actually see it!
So, I would like us to display a small happy face (or something else that suggests high quality) by the HQ releases, and a sad face (or something else that suggests low quality) by the LQ ones. Just the release lists for labels and artists might be a start, or we might want to also show them on search results. I guess we could also do so that if every release in a RG is HQ or LQ, the icon is shown in the overview.
