I think the colour panel design could be improved with a few relatively small changes:
IMO the sliders are too narrow. Changing values using the slider arrows is very imprecise as a 1px horizontal movement moves at least three units of colour - if not more.
There is some wasted space to the right of the entry fields. It would be better if those fields were moved right over to the right hand side, made smaller in size to accommodate the three digits they display, and the slider bars were made wider, using the space that was released.
Ideally I'd like to see the slider bars in this panel 'auto-expand' - perhaps up to 3x their current width (1px = 1/255 unit) when the panel itself is widened.
I'd also like to see the spectrum bar widened to match - and made about 1.5x as deep as it is now. Currently it's too small to be of any significant use IMO.
Good catch, I found several percentages that are not slider selectable anymore for anything with a 0-100% field. Based on some quick tests these percentages are not selectable:
color panel (only in CS6)
92 75 58 42 25 8
layers panel opacity/fill (same as CS5)
layer style popup (only in CS6)
87 37 12
options bar (same as CS5)
I feel the same. The new panels feel somewhat "inferior" to the CS5. Especially the curve adjustment dialog. Jumping between properties and adjustments is also weird - I liked the "back arrow" in adjustments panel more (in CS5)
