Gmail has a feature where you can choose to only show a label in the label list if it has unread messages within it. I would love to see such a feature in Airmail.

Some backstory: I have set up many filters to put messages into various labels (bypassing the inbox) where I treat them as todo lists. When every label is visible at the same time, the UI is a bit overwhelming and it can be difficult to tell which label needs my attention. When labels are only visible when unread messages are within, it's easy to see what I need to focus on.

I attached a screenshot of the Gmail feature.
