I'm noticing that the graph view always shows values relative to the "parent" axis, for example in the next screenshot "parent" is selected and values match:
But if I switch to either "local" or "world" then the graph view keeps showing values relative to the "parent" axis:
My guess is that keys are always stored relative to parent axis but, while editing animations sometimes I prefer to switch to the other axis modes so I wonder if it would be possible for the graph view do a conversion to match the selected axis mode.
