I really dislike the new design. Why not give the option of letting users pick which format they want? I know Flightaware isn’t a forum, but there are a few forums I frequent that after a change, they still offer the older format as well, and users can change back and forth between the two. Yahoo Mail offers that as well.
It’s like where I work where (after new people came in), after things ran fine for decades, things were changed just to for sake of change.
