Showing ELO rating status "outside" of table

[e1q3z9c7]

I just finish a game without ELO rating, and I didn't notice at beginning, I feel like a fool.
I also forgot to turn it ON before, feel really sorry for the winner.
Can you use a small icon or something on the table list to show the status of ELO rating?
Please, let players always make sure their effort is really wroth.
Thank You
