P: LR Mobile Camera: Default Sharpening

I use the LR camera a lot since it has the excellent feature of displaying/shooting in B+W and having the resulting DNG appear in LR as B+W, but with the color info still there. This is great and no other app I've tried has this combo. Seeing in B+W is so different than shooting in color then converting.

A couple of other observations after many shots:

-The default sharpening is 40% for anything shot with the LR camera. It would be great to be able to adjust this. I can set the import sharpening level for anything shot with the phone camera app or a 3rd party app, but not the LR camera.

-One thing I'd like to know is that if the photo has increased sharpening in the Develop mode, is any output sharpening added to this amount? If so, a good reason set a default low or off for the camera.

-The DNG over exposure mentioned in another thread definitely happens on my 13 Pro. Not all the time, but frequently. 

-The shoot through Pro profiles (esp. the High Contrast B+W) are a great feature. I just wish they could be user-modified/created.

-The method of changing lenses would be simpler/faster with 3 different buttons, and not the one that I have to press/toggle through. Floating down a stream in a kayak trying to get a quick shot would be so much better not having to go through the lenses. I almost never shoot Ultra Wide, so that as a choice just slows down the process. And the shot floats away.

-When shooting straight down, the tilt meter comes in handy. When trying to get the camera flat with no distortion, it shows tilt from left to right. But it doesn’t show tilt up and down. In other words, when the lens is perfectly flat, the reading of the tilt meter should register in 2 ways. This is the tilt meter from the Pro Camera app. Easy to see when the camera is flat and the V + H colors align:
