I usually open pd from inside ~/pd_patches and have subdirectories in there. 
If I make a new patch it's often interacting with another patch already in 
the same folder.

Yes, that's better, using "~" as default. And any new patch is most likely 
to be saved in the folder of the topmost already-open patch. And the default 
directory should also be a specifiable option in the preferences somewhere, 
not hard-coded, in the interest of total control.
