+1 for me too. I'm glad the log file is there to allow me to re-do my processing, but it is such a pain. Given that StarTools has a log file I'd been wondering whether it could be saved as a sidecar file or some such, along with the TIFF (or input FITS?), and then used by StarTools to re-perform the sequence of actions. Being able to step through the actions one by one and start taking the processing in a different direction at some point would be very helpful too. As an occasional user of Lightroom, I find that its history feature a really useful asset.
