I find myself frequently leaving a CMS record to check on how it looks in the template, then adjusting the template, then wanting to change something about data structure, etc.

Would be awesome to have a quick link to easily jump from the 'model' to the 'view' and vice versa. Sometimes it's easily to adjust long copy, for example, when you see it in context.

Better yet, for text and rich-text fields, just edit them in place in the view...
