Feature Request - Tree with no icon and no spacing

Currently I cannot figure out a way to put an element into a tree element without either the default page / file icon showing, or some odd spacing being applied through the use of [_] or {space}.

It would be nice to have a property for the tree element to disable the page / folder default icons.

Hi Mike,

Could you also add a screenshot that shows the kind of tree that you are trying to emulate? Thanks!
