A mod to display moment of inertia?

[Zuthal]

I would like to know if there is a mod to both a) display the vessel's moment of inertia tensor along the axes it will be controlled about when in flight (or along the axes of the root part), and to b) visually indicate these axes in the editor, to help with aligning the control component with the principal axes.

Its been awhile since I used this mod - I don't remember exactly what information it displays or how it displays it and, despite the name, I think it shows information on non-RCS thrust too.

I use RCS build aid, and while the torques from engine thrust/engine gimbles/RCS it displays, as well as the dry and average CoM, are useful, it doesn't quite display the info I am looking for. But I found that FAR actually displays those values, so that's fine.
