I visited the page of a beatmap I like, and it made me think it would be nice for the website to have a feature that recommends you similar beatmaps on a beatmap's web page, which have one or more tags in common. The recommended similar beatmaps could show up on the page automatically when you visit the beatmap's web page, after you download the beatmap, or even after you favorite the beatmap. I believe this would add a really nice and quick way to discover more similar beatmaps to ones you like or just downloaded, especially since the recommended beatmaps could include beatmaps with multiple shared tags and even other similar aspects along with that such as approach rate. I also feel it would make a beatmap's web page not only even more useful for quickly finding new beatmaps you might like, but also more dynamic.
