Dear Chimera developers, It seems to me that the manual formation of bonds and building of any type of molecules (not only proteins and nucleic acids), which was a strength of MIDAS, is not supported by Chimera. I would very much welcome an implementation of these features to make Chimera a real replacement for MIDAS.
