WL10 resource-hungry ?

What you suggest does not suit my workflow. I need to apply the same processing to multiple versions of a song - so a WL track has multiple files on it which all need the same processing, but every track is different.

It makes no sense for WL to process track plugins when there is no audio playing. There is no logic to it, so current implementation makes no sense. I’ve made this point repeatedly since at least WL8 and nothing ever gets done about it.
