[Jon Evans <jon@xxxxxxxxxxxxx>]

I'm going to go to the user forum with these questions too, but curious
what the devs think about this:

In my original RFC, I proposed eliminating the different between "front"
and "back" in the Render checkboxes.
I still think this makes sense for things like text and footprints, but I'm
having second thoughts about merging the "Pads Front" and "Pads Back"
Right now we have pads set to a different color than other copper on the
front and back copper layers.
I guess some users probably like this and would get annoyed if we removed
the ability for pads to be a special color.
Will they get annoyed if we force them to set both the front and the back
pads to the same color?

(to be honest, I am used to EDA tools that by default treat pads as part of
the copper layer and show them in the same color, so I don't care about
this feature)
