IMPORTANT: Need to refresh the scroll area once we are done appending data to it.

-sliders might not be visible when the content is too large for the scroll area.
-If you move the slider up or down while the widget displays either events or to do items data,
then switches to the other view, the slider will stay at its previous position instead of jumping to the top of
