HUD that takes you back - where did I see this?

I seem to remember seeing a HUD that would landmark your current location, and then after you had tp'd to another location, you could basically use it as a "back" button, and return to your prior location.

Does this sound familiar to anyone? I don't know if it was for sale, or a freebie, or what.

Thanks,
