I'd like to request a feature be looked into that would re-notify players that it is (still) their turn every 24 hours.  Some people either don't notice often enough or forget to hit "End Turn".

Yep.  Similar things have been asked for before.  

It is always good to ask again because the reason it wasn't implemented may have nothing to do with the quality of the idea.

Agree this would be useful - I've added to the feature request list.
