The <p> insert on enter is common to all html wysiwyg editors.
You can always add/remove smilies by creating a custom button, displaying your own smilies container.
If you use the .Template method to specify the layout, you specify where to put dividers into the toolbar.
The following code add a button programmaticly:
System.Web.UI.WebControls.Image ImageIngressCleanupCode = new System.Web.UI.WebControls.Image ();
ImageIngressCleanupCode.ToolTip = "Fjern Word kode";
ImageIngressCleanupCode.ImageUrl = "../images/cleanup.gif";
ImageIngressCleanupCode.CssClass = "button";
ImageIngressCleanupCode.Attributes.Add("onclick","_Format('rtbIngress','CleanupCode');");
ImageIngressCleanupCode.Attributes.Add("type","btn");
Then add the button to the toolbar:
rtbIngress.toolbar.Add(ImageIngressCleanupCode);
