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. Before I release it, I will make sure that everything is working properly and then I will release it.
Hello everyone, I have watched Manila’s video on HSL Selective Color and I have figured out some of it, but I wish I knew what colors come from moving certain sliders. For example, let’s say I want to make my orange stars more saturated, what would the slider choice be for that and which color would I select? I guess there is a theory to how HSL color works. I love APP and slowly I am getting better with it. Thanks!

@astrohound24 Greg, your particular question about stars only is a hard one since APP currently doesn't allow for that. Also, HSL Selective Colors isn't so much for color saturation but more for changing the color space. In some cases this difference may be subtle but it is important.
If you want to make more orange visible (meaning convert similar colors to appear orange) then in HSL Selective Color you can select the ALL color channel.
Next you select a range. for adding more orange a possible choice could be "background - 75% of range" or one of the "background + X*noise - 75% of range" selections.
You can then adjust the selected range by using the LOW and HIGH sliders.
You can click the "show color selection" button to show which pixels will be selected. For instance, on my image of NGC 7000
selecting "background + 3*noise - 75% of range" shows this selection:
Once you're happy with the selection, you can move the R<->CY and G<->MA sliders both to the left by, say, 30% and click "calculate current adjustments". In my case I get this:
Note that when you use the LOW and HIGH sliders, you'll need to click the "show color selection" again to show the newly selected pixels. APP doesn't automatically update the view.
I hope this answers your question.

Yes this helps. Thanks! When selecting backgrounds I guess one can experiment by checking which selections show which pixels will be affected by looking at the show colors selected tab. I was just trying to make my orange stars more saturated and blues, etc. Thanks again.

One more question. If HSL color is more for colorspace than about saturation, what is good way to increase saturation of something like the brighter stars in an image or anything in the image for that matter? Thanks!
GM
@astrohound24 The saturation slider in the tools section on the right hand side of the APP window would need to be used for that. APP doesn't have masking capabilities to only adjust the saturation of the stars, however.
