 When you add a compound where the SMILES representation is defined, and if the instance is configured to use the Fingerprinting service, a fingerprint of the compound will be stored in the database, allowing the search for substructures.
 
+Chemical structure editor
+-------------------------
+
+Since version 5.2, a chemical structure editor is present in the Tools menu. It allows one to draw molecules and perform operation on them such as searching the compounds database for similar molecules, via a substructure search. This feature requires the compounds present in the common database to be associated with a fingerprint, which is the case if the fingerprinting service is active, and the compounds have a SMILES representation defined.

+OpenCloning
+===========
+
+Since version 5.2, eLabFTW integrates the tool OpenCloning, developed by Manuel Lera Ramirez.
+
+.. note:: To make this tool available in eLabFTW, a specific configuration is required during deployment!
