Show number of completed vs non-completed items besides node text

I use workflowy mostly as TO-DO application for many purposes - work, personal projects, household work items etc. It would be helpful to get some metric at each level of tree - how many completed, how many remaining. I don't know if such thing already exists. Each node should display all child nodes - 56/75 ie. 56 work items out of 75 completed.

Currently I use "completed" filter but this is only localized view. Currently I can not find out progress of two items and compare them with each other to decide where to put more effort or put more people.

Thanks for lovely application.
