ChemDraft 0.3.4

ChemDraw-style keyboard shortcuts, dative bonds for coordination chemistry, and SMILES export that keeps aromatic and ring bonds intact.

• ChemDraw keybinding scheme: an optional ChemDraw-compatible shortcut set with hover hotkeys (rings 3–0, wedge/hash sprouts, carbonyl, gem-dimethyl) and nickname labels (for example e over an atom applies Et). Switching schemes updates the main window, detached palettes, and menu accelerators live.
• Dative bonds: dashed bonds are now coordination (metal–ligand) bonds. They round-trip through MOL V3000, warn when saved as V2000, merge across molecules, and clean up through the layout engine.
• Atom labels: literal labels and naked typed atoms; Delete strips a label back to carbon before deleting the atom, and typed element symbols become real atoms whenever editing ends.
• Charge marks stack up to ±9, and Clear/Restore Warnings works on the current selection.
• SMILES export fixes: aromatic rings are kekulized instead of being written as saturated rings (benzene no longer exports as cyclohexane), a single ring keeps its ring-closure bond order (Kekulé benzene no longer exports as a cyclohexadiene), and bonds of unknown order are written with a warning.
• Structure-list export to SDF and SMILES in reading order.
