Editor: Mouse button bindings in 3D scene
Binding of logical mouse buttons (primary/secondary navigation, primary/secondary edit, select) to physical mouse buttons; plus context sensitive selection mode.
Added this a while back, but forgot to add an issue.
Note: Camera navigation does not respect the button configuration yet.
