Thunderbolt Display window sizes/positions after unplugging

Hey guys!

Thanks to this forum, I decided against the Dell U2713Hm and went with the Apple Thunderbolt Display (so far, i LOVE IT!!!). Now that I've got it hooked up to my 15" Macbook Pro Retina, I'm struggling with the window sizes and positions changing everytime I unplug the thunderbolt monitor and go back to my laptop monitor only.

Is there something I'm doing wrong, or a program that will save my window positions and sizes with the thunderbolt unplugged, then remember the positions and sizes of windows when I have the thunderbolt plugged in (kind of like two little automatic profiles that just work when it's plugged/unplugged).

It's driving me crazy having to reposition and resize all my windows everytime I go back to just using my laptop!
