On Utopian.io many people publish code samples, so i would like to see better support for it here. This better support could be achieved in two ways.
At the moment the editor bar doesn't have a buton for code examples:

Here I would like to see more buttons added, it would be important to add a code button, because it would make the work of many authors easier. Here is a picture from MarkdownPad 2, as a possible example:

GitHub offers the possibility to embed the code samples on other websites. There are several ways to do this. Either you allow to include the provided javascripts that GitHub provides...
... or you go the way WordPress does: you allow oEmbeds. With oEmbeds, only the plain URL of the source (code example, video etc.) is included in the editor by the user and the system behind it takes care of the setup. In case of video, the appropriate player is automatically output and in case of gists, the complete code is output from GitHub.
I would be happy if these two proposals could be implemented in the near future.
