Make yellow cutpoint display connect the atoms that actually connect

Yellow cutpoints are drawn in foldit connecting the alpha carbons of adjacent residues. When working in stick view (to fit individual residues into the ED cloud, for example), there is nothing drawn connecting the carbonyl carbon to the nitrogen of the next residue, even though that is the portion of backbone that is removed from the drawing when a cut is put in. It is very difficult to remember which atoms are supposed to connect, or to envision whether they are a decent distance apart, or whether the backbone angles will be reasonable when the cut is closed. It would be helpful if (in stick view at least) the yellow cutpoint could connect the carbonyl carbon to the nitrogen instead of the two alpha carbons, so we can see what the backbone will look like when the cut is healed.

I think Susume is saying that in stick view, the yellow cutpoint should appear between the C of C=O and the N of N-H in the Peptide Bond shown below:

At present, the yellow cutpoint seems to directly connect alpha-carbon C_alpha_1 to alpha-carbon C_alpha_2 or alpha-carbon C_alpha_2 to alpha-carbon C_alpha_3 in the image below:
