Expanding tree layout and pulling metadata

Hi, I have a couple questions for File Away. First off is there any way to display all info based on the tree directory? Basically I want to show 3 main directories at first, then when the user clicks one directory it expands out so you can see the contents of the directory but you can also still see the other 2 original directories. Does that make sense?

Also is there an easy way to pull the “last saved date” of a file and post it in a column? Basically snagging the metadata from the file.

I LOVE this plugin! THANK YOU!
