Swipe to review
A more intuitive way to review and browse the last taken photos/videos.
Swipe sideways, into and out of preview/browse mode. Paradigm: the camera live preview is presented as an additional card on the end of the row of previously taken images.
See e.g. FreeDCam and OxygenOS cameras.
Perhaps combine this with some more intuitive auto review option, freezing the taken image for a short time.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
