I've just realized that some maps has a very bright background that we can't see the object clearly (like this: https://osu.ppy.sh/beatmapsets/393663#osu/900957 or this: https://osu.ppy.sh/beatmapsets/1028073#osu/2149688) so I would suggest if we can dim the background even inside the editor so that we can see the objects more clearly, to make mapping with bright background much easier to do. What do you think?
