Oh wow, thanks for the feedback. I am really, really grateful. Ill have an update asap.

If the shutter speed get too long, as with many "pro" apps, the refresh becomes slow. Like a mirrorless, best to keep the iso low as poss as the shutter speed to match your needs. Small sensors are not great at long exposures.

I think I may have let it enter burst mode way too quickly if the shutter zone is pressed. Ill fix that...Actually, ill implement a toggle.

Anything else in particular re the fussiness? I would love to make this as good as you expected it to have been for a paid app. Thank you.
