A few comments about ChemCraft.  I use Facio as the front-end GUI and ChemCraft as the back-end GUI for Firefly.  I am able to read input files using ChemCraft.  

ChemCraft will also read the localized MOs generated by the Natural Bond Orbital (NBO) routine built into Firefly.  You do need a license, which costs about $40, to activate the NBO program.  You will also need to include the keyword Plot in the $NBO...$END input group.  To visualize the NBOs in ChemCraft, select Open and then click on File31 in your Firefly folder.  Files 31 to 40, which contain all the orbitals created by the NBO program (including the canonical set of MOs), appear in the left panel of the ChemCraft screen.  In ChemCraft, click on Tools > Orbitals > Render molecular orbitals and then select the set of orbtials you want to visualize.  This procedure may work for localized MOs obtained from other programs, too.  For me, ChemCraft has been well worth the $105 fee.

Good luck.
