one thing that makes life better with existing editor is the fact that when editing a specific section, the section name is automatically added to the edit summary. often, this ends up being the entire edit summary.
- when hitting "save", test to see if all the diffs are contained in a single section, and if so, add the section name to the edit summary automatically.
- just like with existing editor, allow the user to modify or remove this part. i.e., the request is to pre-populate the summary box, not to add section name outside of summary box such that the user can't touch it.
