Color correction
Hugin deals correctly with colour profiles in photos and passes them on to output, this doesn't need fixing, however there are some related tasks that could be tackled:
* Display of images in tabs and preview is not colour managed, integrate lcms and access system monitor colour profiles
* Hugin has a good backend for adjusting white-balance. Add a GUI grey picker and/or tools to adjust colour temperatures manually on a subset of photos to be able to do stuff like this: http://
* EXIF metadata contains information on colour balance (WBRedLevel, WBGreenLevel & WBBlueLevel) which should be used to initialise the red/blue colour balance parameters in Hugin - Currently Hugin does something very similar for EV.
* tca correction in nona with support in GUI and .pto format, possible simple GUI to run tca_correct
