hierarchical lists with collapsing arrows

[Thomas McGrath III]

Martin,

I like this idea very much. Right now I am happy with just using the  
whole line since I don't want to do anything else when clicked but if  
I did want the user to edit the text etc. then I would use this  
approach.

Thank you,

Tom
