set -> Should just set.  No need to return anything :).

Do we need this?  If so, should we just return after this line?

[ltian, 2017/05/23 18:36:46]

Originally, this is a separate check outside the togglerOverview and if true it
will directly call showOverview without animation. So to integrate this into
togglerOverview, I add this for a separate check. 

And yes, it should just return, thanks for pointing this out.
