Thanks Mike, will definitely check this out. I've been working on 1.3.0 so missed the addition of this.
I'm assuming that the playback is performed in a memory-efficient manner and doesn't require the entire recording to be loaded prior to playback (as, if I recall correctly, was previously the case for the sample in-browser player)? Thanks again, Andrew.
