Sublime Text expose the Default folder and the Preference.sublime-settings file (and others) while keeping them read only. This is an awesome way for users to learn how to use it.
Does Sublime Merge have a similar default .sublime-commands file that defines the existing/out-of-the-box commands in command palette? This would be a great way for users to explore and learn the full power of custom commands via copying and tweaking in User/Default.sublime-commands .
