Jon, sorry to be picking on you again :) but I have comments on the new command you added to View":
- "display adjustment" is too generic. It may mean a lot of things. The statusbar tip explains it, but why not rename the command itself to something like "display color management" or "display CMS" etc.
- if it's a toggle, it must be presented as a toggle and have a check mark against the command name in the menu.
- if you cannot yet disable the command on displays where it does nothing, you must at least provide some feedback when the command is invoked - the statusbar must flash one of "display cms mode turned on", "display cms mode turned off," or "cms mode is not supported by this display."
- what about windows? mac? if it never works on windows, please make it compiling conditionally, and mention that it's X-only in the release notes.
