"greyed out" buttons in UI need to be represented somehow

Minor issue - but if you're using an interface like the Views 2 one where while you are editing a particular element of a view, the overall display buttons are disabled (so you can't save a view while you're half way through configuring a field, for example) then the current RootCandy buttons don't show this. The green "Save" button stays the same. It should turn grey with a tinge of green, or something like that, to show that it is temporarily disabled. Otherwise people who are not familiar with a module that disables buttons during actions could get very confused and think something is wrong.
