Code Editor and Ajax Save

This plugin is very cool. Nice work. I want to make two suggestions:

1 – add a code editor to the main textarea, like CodeMirror
2 – allow Ajax save, like in WP Posts. Actually I have more than 30 codes and is bad the save-test-search for code-edit process. A simple save. without page reload, would be nice for testing porpouses
