Rags Hi Rags simply put NO you cant.
If you want gaps between songs don't auto scroll and manually start every song as required which is most solo performers preference, but if you are a DJ and just play tracks in Auto play mode you could edit in silence at the head of all your tracks to give you this gap and ST3 has a trim feature which can shorten this silence.
Yes it would be nice if there was a time delay setting in options to create a gap of choice to all auto play songs but Peter is very busy working on more important features i think this might be useful for some users but its not that much of a problem and can be achieved if really needed perhaps not in an easy way.
Good luck Damir
