I wish there was a way to save progress automatically when an error occurs while reading the disc.

For example, if there's a power outage, or the disk is dirty. I'd like to be able to resume where I left off when I put the disc back in. I know other utilities allow this. Thoughts?

Others have suggested something similar, wanting to be able to resume making a backup of a disc. https://forum.makemkv.com/forum/viewtopic.php?p=156956#p156956

The program's author, Mike, has even talked about such a feature. I don't know when or if it'll ship.
