What if the current view in Google Earth was quickly viewable in other maps, such as those made accessible by FlashEarth? Well, now it is. As you move around the globe a little white arrow follows you around, simple click it to get an approximation of the current view in FlashEarth in a popup balloon.
Total credit to Valery35, for the concept (including a screenshot) on the Google Earth Community. (and to all the people made all the bits that could be pieced together in this 15min hack)
