I've needed something like that for a long time. So in the mean time my solution has been to have a watch or clock in sight, and a pen & paper nearby with which I jot down the time anything noteworthy happens.
Then I just look thru the films, and looking at their windows creation timestamp I can pick out which films have what in them.
And if HiTech happens to read this... We still want that post-flight statistics dump..
