Two brief comments on observations: - Some of the Hill formulae, multiple of the structure formulae (either `Chem.pdf`, or `ChemO.pdf`) are in bad condition. Examples include the Calcium sulfate dihydrate, the distorted lactam cycle of Penicilin, the shattered porphyrine backbone of chlorophyll, inconsistent single lengths of single bond in the core vs the side chain of cholesterin, etc. - Briefly browsing file `chem` as shared by you, some indentations are defined by spaces, others use both (spaces and tabs). I suggest to opt-in for either tabs, or (2 [perhaps an earlier default?], 3, or 4) explicit spaces per level of indentation. Kind regards, Norwid
