I`ve been working across platforms with another photographer and we usually share catalogs so that he refines the work and properly calibrate the colors on his macbook pro (much more reliable than my Dell laptop) and we usually need to communicate ideas and notes on each particular photos. What would be awesomely cool yet very simple would be to have small tag/balloon overlay on the photograph itself, that you can toggle on and off, where you could write short notes and ideas.Sometimes you realize after recalibrating your screen that your pictures lacks warmth or you need to trim up or down the contrast on all the pictures. What would be interesting in this situation rather than either synchronizing all the photos to one setting or to do it manually as each photograph has particular needs, would be do have a feature where you can synchronize a trimming value. e.g If all your photos lacks warmth and you cannot synchronize all photos to one Kelvin value, you could synchronize it to + 250K or if you wanted more contrast overall you could synchronize all the pictures to +2.5 contrast. In essence it will shift the particular value to +2.5 or +250K.
