The calibration features look great, and it's great you added hot pixels. You could add one more box: "Run Map1". The documentation would indicate that if people save their bad column pixel map as "Map1", this checkbox would execute it.

As you might recall, I handle this with User Actions. Almost everyone will have some bad columns, so this is a way to enable people to remove the bad columns particular to their cameras.

Just an idea since you're working on this.
