Note @ 2024-07-18: Due to another YNAB Price Increase I've decided to leave YNAB for Actual and therefore unable to maintain this extension (as I don't have access to a YNAB account).
YNAB accounts page allow you to flag transactions with a color, this extension enhances the functionaltiy by highlighting the entire transaction row with a lighter version of the same color.
