For non-techy editors who don't know much html or css, it is difficult to start some articles from scratch, especially if they'd like to keep it more or less the same format as existing articles.

At the moment, the only way to do this is to:

1. open an existing article,
2. copy the code,
3. close the article,
4. start a new one,
5. paste in the code and then
6. Edit

Describe the solution you'd like

Add the 'Save as Copy' option to the front editor so,

1. Open article
2. Click 'save as copy'
3. Edit
