Rotation lock options

[Nixill]

OpenCamera has a habit of always rotating images to whichever direction is closest to the Earth's core, even for very tiny differences. This gets annoying when I'm trying to take pictures with the camera pointed straight down, because the UI doesn't rotate like that unless one side is clearly pointing down. This results in frequent lopsided images of documents.

For example...

Here's a screenshot of the camera just before taking a picture:

And the picture taken at almost the same moment:

I'd like an option to always lock the camera rotation to match the UI, or a toggle to lock it to current, or something that would stop me having to open the image editor to correct the problem with nearly every downwards picture I take.

An elegant solution to this could be to use the gyroscope to detect that the camera is pointing down, and disable image rotation in this case.
