Where's all my coal going?

This shouldn't be too hard to add. There's already a list of recipes by material (right click coal, for example). This would add a statistics page similar to the in game recipe list, but for each consumption recipe, it will show percent of total consumed over the last year, total quantity over the last year, and average quantity per minute. Also, sorted from highest to lowest. That way it would be easy to see that x% of my coal is going to power production (coal to steam recipe), or whatever. Could also add info on the production section, to see where materials are coming from.
