Since you brought vnodes into the topic :-)
Building large data visualization (i.e. throw away) trees is slow with
positions, but fast with vnodes. I use this monkey patch:
from leo.core.leoNodes import vnode
if not hasattr(vnode, 'insertAsLastChild'):
def ialc(self):
vnode(self.context)._linkAsNthChild(self, len(self.children))
return self.children[-1]
vnode.insertAsLastChild = ialc
