Stop playing In The Air Tonight during pre-game. I'm sure there are newer songs/music that can be played.
Figure out why the Club TV's that hang over the sections are on a 3-4 second delay from the big screens. I've got a club tv and big screen in my line of sight when watching a replay, and it's distracting that the video on the club tv is behind the audio and video on the big screen.
Someone earlier mention charging stations. The formerly heated club seats had power running to them for the heating elements. If the conduit and wiring is still there, they could put in outlets at every seat for people to use their chargers with. It would be an additional selling feature also, being able to charge your phone at your seat.
Rip all the seats out of one of the corner sections, like 118 or 125. Put up railings with cup holders in each row. Sell those sections as standing only for those fans that want to stand the entire game. If it seems popular enough, do another section the next year.
