I've always planned to build a pair (at least) of file format specific GUI tools. The first target would be JPEG, and the second PNG. The JPEG one would primarily be a GUI incarnation of the IJG's neat extras like "lossless" crop or rotate and other operations which make no sense in a format agnostic tool like Gimp, I will add "change metadata without touching image" to my wish list -- not everyone wants to use the CLI in the middle of an image editing session.
