Actually the problem is that they are treated as "usual" 2D curves, and
are allready in automatic mode. What I propose is a mode that don't
exist and don't make sense for 2D/3D curves. It only make sense for
animation curves (curves for which the x is the time and y a value of

What do you mean? By default blender already use bezier and default
bezier automatic handles.
Automatic handles is what I consider as an issue for IPO curves since
they are adapted for 2D/3D curves but not for "time" related ones.
But you (and every else one as I see) have the right to disagree with this.
I was just proposing this since I though that is was a good and
animation-compliant automatic interpolation.
I think I'll simply keep my little script.
