Yep I'm using mac 10.5.8
Your post is the first time I've seen that name,
I believe the "folder merge" option was added to OS X around 10.6 or so.
You need to get out more often! It was first reported in our rumors forum right after the announcement by Apple.
OS X Mavericks was announced on June 10th.
One wonders then if we continue down the OS X path, up to OS X.XX ??
