hey Pablo, I think you can skip the timeconsuming process of having to jump to step one manually in order to do the forward recording. If you just hit FHistory while the end result is the current "state", ZBrush does that jumping back for you. Not sure, but I think your approach was necessary in an earlier version, but not anymore.
if you are working with multiple subtools, you can't really use F/Bhistory since it is applied only to the selected subtool. What you COULD do is use the "Timelapse" feature in the "movie" tab to record all the subtools that are being added and modified. This, however, will yield a different final video, which shifts the camera around as you work. Another possible option is to use Fhistory and record each subtool separately, and then somehow combine the individual subtool timelapses in a Video Editing Software. I hope this shed some light on that
