Custom Classifier Sliders (ordering problem when adding more classes)

What steps will reproduce the problem?
When I open the Custom Classifier via GeoMap, the classification sliders
are spaced according to the number of classifications I have.  When I add
more classes (say, from 3 to 7), the new sliders are all placed on top of
one another on the right-most slider.

What is the expected output? What do you see instead?
The enhancement I would recommend would be to space the new sliders out
evenly when you increase the number of classes.  As it stands, you have to
"unstack" them from a right-hand pile, then ensure in unstacking them that
you maintained the correct order.  Otherwise, you can accidentally put
divider 4 to the right of divider 5, giving you a 0 value for that class
until you put it in the right order again.  The first problem is that it's
not clear that all the additional dividers are stacked in one place.  The
second problem is that when you unstack them, you can mess up the order. 
The solutions to the second problem I see are:

1) Place a number above or inside each slider so you know the order they
are supposed to be in.
2) Don't allow the user to move the slider for a lower class to be higher
than the next class' slider. (for example, the slider for the 3rd class
from the left can't go to the right of the slider for the 4th class.

What version of the product are you using? On what operating system?
Using the newest (?) version with the 2008 election data.  It says 0.8.5,
but I think it might be newer...

Please provide any additional information below.
