My first attempt at viewing molecular compounds. The .mol files I used are exported from molview.org. These contain the x,y,z coordinates of the atoms/bonds, atom type, and bond type. Click and drag the mouse to rotate.
Representation of covalent bindings in a different color (red) than simple bindings (black). Actually TheMoSmiths's code had quite everything ready inside to implement in such way, I guess he foresaw it intentionally. Congrats btw. I suppose adding one item in new Lines.Colors table will suffice to also distinguish triple liaisons from the rest. This is not what you wanted @TheMoSmiths, but it's what @gtoal was looking after. Now thinking about a way to represent real double lines...
