Flag to indicate potential AFK's

The start of the game has many factors going in…

I was wondering if there was a way to notify active players, perhaps about 12 hours ahead, that any particular player has been inactive for the prior 36 hours, thus on the way to AFK.

That would allow remaining players to jockey for position, plan how to carve out the eventual AI empire.

For turn based games, maybe set the notification flag 1 turn jump in advance.

This would be nice, though it’s doable in a fashion already. I track the intel charts to see who hasn’t been upgrading their infrastructure as my way of telling who is likely to go AFK.
