[Chimera-users] Adjust angle

Since Chimera allows you to change bond lengths and torsion angles,
it would seem that just as a matter of completeness it should allow
you to change bond angles as well. So despite that not being a
commonplace desire, I will add it to my to-do list and open a feature-
request ticket in our Trac database with you on the recipient list so
you'll know when it gets implemented. It may take awhile (there's a
request for chirality inversion in front of it), but it'll get done
P.S. In case you didn't know, you can set bond lengths in the "Adjust
Bonds" tab of the Build Structure tool.
