> Here it is and it's huge! I've been on vacation for the last week and haven't had a chance to do much coding. :-) But I wanted to ask if it's not too late to add two or three small features to the VERSION_2 branch before we release. * H -> Methyl * Selected H -> Methyl * Add Hydrogens to Selected I think these features would be self-explanatory. Like the hydrogen addition we currently do, these can be run through Open Babel. Basically I've recently found myself wishing I could just add missing hydrogens on a few atoms and not wanting Ghemical touch the rest of the structure. If this sounds good, I'll try to get the code done today. Cheers, -Geoff
