Why do we have two Apply buttons in the classifier interface. Do we need them?
The button Tips are:
1. APPLY: "Apply changes to selected class"
2. APPLY: "Apply changes to map"

APPLY 1 does not do what it is suggesting and I am not sure if we really need to
have this button on this interface. I think that if a user changes the symbol or
a Label they should, use the Apply button on the Fontalizer and Symbolizer
interface.

I also think the that the Apply 2 button functionality should be where Apply 1
button is. And have the "Close" button , Apply and Close Classifier Window.
