Child counter?

Hi!

Thank you for this plugin, I have searched a while now and finally found this plugin (it should be easier to find it!).

However I have a suggestion to your plugin, in order to develop it further.
Is it possible to put a counter on each nav item that have child items, kind of child counter?

See this plugin http://www.farinspace.com/wordpress-sidekick-plugin/ that we use for the moment but need to replace it because it hasn´t been updated in many years.

Thanks in advance! 🙂
