Timer should have warnings

I have had several games end because I was not wary of the time. Since every game is variable with user determined minutes and +sec every move, most of these games have been because I simply didn't
realize I was low on time that game.

A warning noise or a flashing timer drawing subtle attention that I am about to run out of time would go a long way.

Also, this website is fantastic. I love it here.

No, there shouldn't be any warning since there is no warning when using real life clocks. Each player needs to be aware of the amount of time that he or she has left.
