Correct & that's now partially been achieved with the recent betas but isn't going to be the default mode for a while until the eq & modern skin support aspects are resolved. As due to what I'm trying to offer, things like some of the filenames are going to have to keep the winamp related names as that's the only way to offer the compatibility that I'm going for - that's the one thing that I would like to not have to do but for now it's got to stay.
As such I don't really see a need to change the WACUP name (much like the meaning of WINE has changed over time but is still called WINE) not that anything has come to mind from some prior thinking as this has been asked recently elsewhere.
