I would love to have a button on images in Jerboa that would completely invert the colors of an image. My retinas keep getting burned when I’m opening a post on my dark themed phone that is of a white image with text. It would be great to be able to view/read the image this way.

PS double tapping an image zooms it in waaaay too far. It should zoom to 100% size. My biggest pet peeve when trying to enlarge images.
