I think that we all like things to do what they say on the tin.
The “Cross Fade In” and “Cross Fade Out” effects do not perform cross-fades and IMO should be replaced by an effect that does.
I would like the “Cross Fade In” and “Cross Fade Out” effects to be replaced with this (one) Cross-Fade effect: https://forum.audacityteam.org/t/cross-fade-revisited/21408/1 (or something much like it).
This effect includes the functionality of both “Cross Fade In” and “Cross Fade Out”, and more importantly it can do a cross-fade.
