 - add borders to UIView styler: st.borders = {l: {w: 2, color: color.black}, r: {w: 2, color: color.black}}
 - add templates for: nav controller, tab controller, table controller, collection controller
 - add from_right, from_bottom, and centered to both st.frame and to move
+- add binding that combines KVO and events to bind an attribute of one object to the attribute of selected view(s), keeping both in sync, like so: rmq.append(UITextField).bind(@person, attr: :name, to: :text)
