Thanks! Requests (1) we have identified the variable in each object that allows us to match these objects to opflashes in the event. (2) add comments in the header to describe what these are. at the very least comment on the variable that gives the time. this is the product most used by the end-user. I can volunteer to add the comments as long as someone is willing to check that the comments are true.
