Be able to use "and" with label filters
Admins use various labels for ideas. They often need to filter to find ideas that have at least two or more labels applied. Currently this is not possible.
Let's say I have Label 1 and Label 2. Some ideas have both applied, others have only one of the two applied.
If I check the filter for Label 1 and Label 2, I will get ideas that have either Label 1 or Label 2 applied or both. They want only ideas with both Label 1 and Label 2 to show.

This is critical for large organisations. One of your competitors handles this by adding a drop down box at the top of the label selection to allow you to choose from "Any of selected", "All selected" or "None of selected" which does exactly what we need.
