@v1993 +1 on this question. Maybe it is a planned (future) feature but when I saw it I thought maybe it played the first 30 seconds (or some other duration) of each track in a playlist. I've tried enabling it before or after loading a playlist but nothing really seems to happen. Just curious.
I understand there is currently no Mac developers involved in the project. As very nice I am finding Strawberry it lacks one feature I find necessary, the ability to wirelessly connect to my home Hi-Fi.
I am requesting this feature be considered at some point.
