All buttons are added to your toolbar automatically until you reconfigure that. You can also visually configure templates of widgets right from the configuration dialog of N1ED or from Dashboard.
Insert YouTube videos: search for them right from N1ED and insert a fully customized widget into CKEditor/TinyMCE.
