-Destroy widgets when the container is destroyed.
\ No newline at end of file
+Widget alignment.
+Widget horizontal/vertical expand.
+Destroy widgets when the container is destroyed.
+Homogeneous sizing for list items.
+Allow setting list direction. This is more efficient than prepending widgets to a list.
+To do not render widgets outside the current scissor (or window). Also stop rendering scroll view when reaching outside the scissor view.
