While the extra text in the buffer is helpful while watching a film, personally I found it sort of distracting to have to look down at the buffer and then back up again to see what was done. Unless you pause it at every moment a message pops up to analyze it, I guess.
Tools once posted a video on throttle management talking to himself on vox as a way to narrate his actions - I found that to be really helpful. But following text in the buffer while watching film is far too distracting, IMO.
Like Moot says, a followup on the thread is usually sufficient.
