Wow. The interface in Poser 7 is so much different than Poser 8. Well, not really. But "collections" is where you can store your most often used poses, props, characters. In essence, it's a "my favorites", right?

In Poser 8, that tab is called "Favorites", but the folder for it in my common files is called "Collections".

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
