Add the G'MIC Chromatic Aberrations filter in GIMP
There is a filter in the G'MIC plugin that I use a lot, mainly to make art in the Retro Wave or Lofi style, called Chromatic Aberrations. With this filter you simply choose two colors from the image creates a distortion in those colors creating this effect:
It would help a lot to have this native filter in GIMP, as the art styles that use this filter have been in fashion for a long time, especially among young people.
(I'm not sure, but an effect similar to this can be useful for creating images for use with 3D glasses)
