Zoho Notes (not in list of forums): increased flexbility?

Hi,
 
I would have added this to the Zoho Notes forum... but there doesn't seem to be one! :-) I'd like to see the capability to create a tree structure of the categories, but more importantly to assign a given note to one OR MORE categories, and then be able to filter per category. Are there plans to do this?
 
Thanks,
 
Paul
