Market holidays or long weekends

This is a humble request to add a feature that notifies users on the home page about an upcomming holiday or a market holiday coming up on a friday. This at times becomes very important to square off positions. Holidays is something a trader might think at the very end and possibly after market hrs in most cases. If there is a running marque at the top which notifies about an upcomming market holiday, it would save many traders to square off their positions and have a peaceful weekend of time off and not live with a fear of where and how the market opens when it does. I personally have got caught in such situations, so it might be a good idea to add if it doesnt hurt.
