I'm new to using UI Builder, it is a wonderful experience. This makes creating an editor UI easier. However, while I was busy creating elements I didn't find a way to recreate the Toolbar GUI. I can create it via C# and add it manually but it would be nice to have it available through the UI Builder somehow. It's a style that I'd like to apply but how can you apply an existing editor style? i.e Toolbar and Toolbar button.
