Settings, available here:

> -   Text wrap: controls if the text in the editor should be wrapped.
>
> - Enable optimization: defines if the compiler should enable
> optimization during compilation. Enabling this option saves execution
> gas. It is useful to enable optimization for contracts ready to be
> deployed in production but could lead to some inconsistencies when
> debugging such a contract.
