It is not a best solution, but until the complete desktop is colour
managed, it is needed to have a chance to switch to sRGB emulation.
Otherwise, the window decorations and images in non-colour managed apps
look unrealistic.

I agree. GCM would not only provide a default profile for each device
type (one for 5D, another for D200, etc.) but also a list of potentially
usable profiles, which were previously assigned by the user for the
particular device. The advantage is that the list of available profiles
gets shorter.

only to change the profile or rendering intent for a single photo. This
option must be available directly in the app (RAW converter, editor).
