So the suggestion got a hell of a lot of support on the Reddit post, as well as some supporting comments here. Peppy also gave some thoughts and said he agreed the game needs this and if something like this were to be put together it's almost guaranteed to be bundled with the game. I have very little mapping experience and next to no experience and connections in the community, but what I do have is programming experience. So I'm hoping that if I put together a platform for this to work on in Lazer it'll push the rest of the community to come together and provide the content. So that's what I'm going to do ASAP. I don't know how long it'll take, something like this is theoretically quite trivial from a technical perspective, but I have no experience with the osu!Lazer framework so we'll see how it goes. I'll likely post somewhere more appropriate once work is underway.
