Think of methods as a pseudopod of a folder, not a entity unto itself.  They're best used for DTML code that has at least folder-wide scope, in my experience. I try to push as much presentation logic into methods as I can, and use DTML documents as content objects.

<dtml-tree expr="PARENTS[0]"> 

will make a tree starting from the folder above the DTML Document.

<dtml-if "meta_type == 'DTML Document>
<dtml-tree expr="PARENTS[0]"></dtml-tree>
<dtml-else "meta_type == 'DTML Method'>
<dtml-tree expr="PARENTS[1]"></dtml-tree>
</dtml-if>

might be what you're looking for.  Feel free to add branch_expr etc.
