See those Trello cards you haven't touched in X (reportsfortrello.com)

Want to see the just the yellow labeled cards that are in the same list across 20 boards?

I just added a low friction way to see such things.

PS - Sorry world for the bug that took me 6mo to fix. There should be less errors.

This tracking only works when cards have been moved onto the "doing" list and off it?
