Topic notes word count

I often use MindManager to write articles. The ability to create a provisional overall structure in which I can add text as topic notes to different sections makes it easy to work in a non-linear way. While I would like a much better text editor, the topic notes facility is also less distracting than a dedicated word-processing program like Word.

However, articles for publication often have strict word count limits, and when you work this way it's hard to keep track. It would be great to have an option to show the word count for individual topic notes. Ideally this would be made available as a topic property that could be rolled up to show the overall word count total.
