Back Button, Places Column Tip

Back Button: As I move around in GEarth, GMaps and other mapping systems it occurred to me that I’d really like to have a back button to fly me back to the last view or back to the last placemark I looked at similar to the way a browser back button takes you back to the last page. You could have a whole history recorded like a GEarth tour which you could replay until you found the location you wanted.
Places Column Tip: There are 3 parts to the element listing in the GEarth places column which can be clicked with different effects. I use this most times I have GEarth open.
