Double clicking node causes form to render.
Fields related to node display and show correctly based on selected POS, and based on config filters.
Fields display in edit panel on dbl click node.
More responsive CSS, form fields populate if a node was displaying them, and then another is clicked
with the window still open. Can close the edit props window. Styling for these elements.
Need to commit because I'm losing my mind trying to get this silly points circle
to use the CSS animation. Otherwise, the tree now updates all nodes that are children of the
root automatically when the tree is otherwise complete.
