It would be useful to have pings on the map when a ship, a bomber, or a sub has reached its destination waypoint.
I lost a game once only because I forgot about my bombers that had reached their destinations and turned back dying from enemy fighters.
I think many players forgot about subs lost somewhere in Pacific while their attention was elsewhere.
I suggest adding some kind of notification (a ping on the map similar to the one we see when there's a launching sub) to a player when his units demand his attention.
A flashing tray icon for games that drag for hours would be nice too.
The same ping can be used when a unit gets under attack.
