- Curve editor. Linear curve editor is nice, and would suffice, but parametric (highlights/lights/shadows/blacks) would be another level, because of ease of use.
- Framebuffer LUT support. Great feature that extends the usability of framebuffer to any kind of post-production feature. It's not just for instagram effects from imitating old polaroid films. But even that is cool ;- )
( alternatively, people with color managed environments would benefit from ICC profile too, but this is secondary )
- White balance compensation. Not just Kelvin, but selecting a spot in image to counter-balance. Just like in real-camera. Both temperature and Tint.
- Better contrast function, similar to CameraRaw. Ideally the same one. Posted a separate thread.
- Glare and Bloom is being worked on, so, that's checked off :- )
- Make the GUI detachable. Unless you work in 21:9 monitor, which 99perc. of users do not, it takes endless space and occupies rendered image. If it's switched off and back on, the framebuffer needs to be full-screened for docking, so this is not very flexibly working.
-Simple button to disable all post-production. On/Off. Absolute must to see the changes, save linearly and not destroy already fine-tuned settings.
