osu! difficulty filter

osu! difficulty filter allows you to show beatmaps on osu! userpages based on difficulty. Using the sliders or text inputs, you can enter a difficulty range, and it will hide the beatmaps that are outside of that range. You must have a registered osu! API key to use the extension. For the beatmap listing, it is recommended to use the "stars>/<(=)" search term to filter beatmaps by difficulty.
