Just a suggestion, I thought that if you could add a setting that pulls the mirror up before taking the picture; that could reduce camera shake. Maybe add a setting that let you decide how much time to keep the mirror up before taking the picture.
JUST an idea from a guy that has NO experience in this but knows it's a challenging thing to do. So if you think this would be worth adding, that'd be awesome. But I definitely don't expect you to do it if you don't want to

I'm very happy with all the features you've already added and I don't want to be a pain. Thanks for all your work!
@BrightGarden, I just turned my setting, touch to shoot, off, went to HDR and back, but the setting was still off. I guess I don't have that problem. However, I have noticed that it's turned on a couple of times without me setting it... I thought I was losing my mind, I guess not.
