 ## features
 
-- nest transaction support (using `savepoint`)
+- nest transaction support (using `savePoint`)
+- check integrity (`integrity_check` pragma)
 - precompile querys for performance
+- get or set db version (`user_version` pragma)
+- optimize pragma (typesafe `journal_mode`, `synchoronous`...)
+- create kysely logger
