show_code and "Cell output area" above or below

[moble]

Description

I think many people who are used to IPython notebooks really struggle with seeing output above the code that produces it. The "Cell output area" option is great for this. But show_code appears to only show the code below the output. Particularly for app view, I think it will be much clearer to users of my app if they see the code, and then the output

I think this function should

1. Have an option to specify whether code should come first or output.
2. If the option is not present, go with whatever is in the settings.

Suggested solution

The first item seems easy enough; it would just be an option to the function that would reverse the order in this statement. But I don't understand the settings system enough to figure out item 2.
