I browse to a folder, then expand through a directory tree to find the file I'm looking for. Now I want to create a folder at the current location within that tree.

1. "New Folder" from the menu creates the menu in the top-level directory instead of the current directory.
2. Right-clicking doesn't give any way to create a folder "in-place" - ie with reference to the file or directory I currently have clicked/highlighted.

Simplified example (thanks soulshined):

/Users/user/Downloads/
/Users/user/Downloads/Pictures
/Users/user/Downloads/Pictures/pic1.jpg
/Users/user/Downloads/Pictures/pic2.jpg
/Users/user/Downloads/Pictures/pic3.jpg
/Users/user/Downloads/Pictures/pic4.jpg
/Users/user/Downloads/Pictures/pic5.jpg

The finder window is opened on the /Users/user/Downloads directory, but I have used the tree-expanders to be looking at the files in .../Downloads/Pictures.

I want to add a folder under Pictures, but irrespective of how I invoke it, the new directory will always be created under Downloads.

(Obviously in this example it would be trivial to move it, but imagine the folder is a byzantine corporate shared directory tree,...)
