GoLive is very extensible. In addition to an abundance of preferences you can set for things like window sizes, publishing servers, project settings, default browsers, and code color syntaxing, GoLive gives you options that can change the way GoLive works at its code. You can change anything about the way GoLive codes your pages, including adding custom tags. You can extend the interface by creating your own objects for the Objects palette, add code Snippets to the Library palette. For those more adventurous, Adobe has released its GoLive SDK, giving you even more ways to customize GoLive's interface.
