UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
If I have a large number of light frames with vignetting, can I set up a vignette coorection on just one of the light frames then apply the results to all of the lights?

Not in software. You could make an artificial flat if you don't have any dust spots etc and apply that to the lights. But other than that you would need a real flat which is always better.
Thanks for the reply. But I am confused about how the vignetting correction is done in APP. If I can only correct vignetting on individual lights, there is an enormous amount of repetitive calculations to be done. What is the value to only being able to correct one light frame at a time?
