Thanks guys. The badge is a nice bonus but really seeing people getting some use out of this is its own reward.

Jfrazierjr, thanks for the suggestion. I've often zoomed out or in and then lost my forest, and grumbled under my breath about it but it never registered enough for me to do something about it. Rest assured it will be addressed in the next update.

And thanks everyone for the info on vectors. It will still be a case of, "when I get time" but I guess it will give me a head start in my studying the possibilities.
