Cholesterol in 3D
- Caffeine aromatic rings appear as circles in the default SMILES layout.
- Paclitaxel's automatically generated layout has overlapping methyl labels.
- Cholesterol SMILES opened as a flat structure in the 3D viewer.
- The 3D SDF import became 2D and showed an AND racemic stereo group.
- The default PNG export reports 72 dpi; a 4× print option is offered.
