Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.
Is the chemistry checked?
Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.
Do the Lewis structures show lone pairs?
Yes. Every lone pair and formal charge is drawn, as most syllabuses expect.
