+1  One way to do this is to search by each label name and manually go hit the filter and see how many results show next to the label of that same name.  Not very efficient.

Labels mgmt is a big area of opportunity for Igloo.  Examples:

• Can't see which labels are being used and drill down to see specific items that use that label
• Recent Activity widget can't filter by Label
• When adding a label, you can't search for it - you have visually find it on screen
• In the search page, you can't just search by label - you have to have something to search for before you can filter by label - what if I want to see all content with that label?  You can't.
• Filtering by a label on the search page is somewhat cumbersome already - I'd like to see the advance filters displayed horizontally above the search results so you can quickly hit one drop-down instead of two
• There doesn't seem to be a search operator for labels, such as "label:bestpractice" to find all items with that label
• The workplace analytics doesn't offer a way to display metrics per label.

Ok, got it. Thank you for entering a feature request for me.
