- Import from/export to .sdf, .mol
- Import from/export to RDKit molecule
- Molecular property calculation (MW, Chemical formula)
- Descriptors

- H-bond donor/acceptor
- Wildman-Crippen logP
- Aromaticity

- Molecule graph topology (ring, scaffold, connectivity)
- Sub(super)structure search
- MCS with diameter restriction (MCS-DR) and graph-based local similarity (GLS)

Features (WIP)

- Functional group descriptors
- Markush structue
- SMILES and 2D coordinate generation

Features (will never be implemented)

- Python 2 compatibility
- Fingerprint similarity
- And many of the features already available in RDKit
