If your capture details aren't changing (center frequency, bandwidth, etc.,), then you can stream the annotations as they are continuous, but you can't hop back and forth between them. This is an interesting point, though. Would you mind raising this on the SigMF tracker for discussion, Bastian? Cheers, Ben
