You might also consider an option to delete silence at the end.

Bump.

Wxx is still useful for compability and if you want to force how the module should be played.

But fade-out in stream-export is useful if you're making streamed music with OpenMPT and want looped music with a clean fade-out, as Wxx fades out the linear global volume in steps, which can be heard especially in the lower volumes.

It also saves time in compo-context as the Wxx-method is a bit slower, whereas you have to duplicate the "loop-start" pattern and flood-paste Wxx, or do a trick with Wxx in the loop-start pattern and make it start fading once the song loops.

There's so many possible parameters to change here (duration, fade curve, etc.) that I think it makes more sense to do these sort of operations in a dedicated sample editor (or the built-in sample editor if 16-bit resolution is sufficient). Makes it much easier to review and potentially re-do the change, too.
