 # Controls are arranged in a list in self's bitmap. Each control is given an
 # area of size "self's bitmap's width" x LINE_SPACING to draw itself in.
-# TODO: The act of "capturing" a control makes other controls in this container
-#       not update themselves, i.e. they won't colour themselves with a hover
-#       highlight if the mouse happens to move over it while another control is
-#       captured. Is there a better way of dealing with this? I'm leaning
-#       towards the control itself deciding if it's captured, and it being
-#       treated as uncaptured once it says its value has changed, but I think
-#       this would require manually telling all other controls in this container
-#       that something else is captured and they shouldn't show a hover
-#       highlight when updated (perhaps as a parameter in def update), which I
-#       don't think is ideal.
