884	need more tether positions on ribbon	Greg Couch	Conrad Huang	"When drawing nucleotides representations, ladders and sugar tubes, would like to connect directly to the ribbon, instead of an atom tethered to the ribbon.  Ideally that would be where the plane of the base intercepts the ribbon.  Chimera1 uses the spline position halfway between the C5' and the O3'.  But a functional approximation is the C3' tether position on the ribbon.  Would also like the ability to tether a second atom to the ribbon.  The second tether would also be useful for proline.

So this is a request for the tether positions of the minimal backbone to be cached."	defect	closed	major	0.5	Depiction		fixed						all	ChimeraX
