This has been in the back of my head for a while. I'd like to ignore all graphical skin elements of all beatmaps, but would also like to keep the combo colors they use. The reason for this is how some mappers incorporate combo colors to mark changes in slider speed (e.g. http://osu.ppy.sh/s/45074) or general tempo of the song or other aspects. This use of different combo colors can help immensely when playing, which is why I don't (want to) ignore beatmap skins globally. The problem with this suggestion is that there's a potential new per-beatmap setting; maybe it could be added as just a global option, and the per-beatmap ignore setting would still ignore the combo colors of a beatmap. Not sure.
