CameraTweak, one of the main reasons I jailbreak for, is now iOS10-compliant!!
What I hope for is raw / DNG support for 12 Mpixel models (where DNG is supported in iOS10). I've mailed the dev the following:
"I think it’d be GREAT if you offered a way of (also) saving the image into raw / DNG files. Currently, one of the biggest problems with the stock Camera app is the lack of DNG saving support. One needs to use 3rd party apps to save raw’s - with all their problems; for example, no live view or Apple-like HDR support. It could be just an additional switch in Settings en/disabling it - that is, no separate GUI changes would be needed. "
