I spoke too soon when I said I was good with the appearance of the web page for the builder on the survey. I hadn't actually worked in the builder yet.
I don't like the trend for all the low contrast web pages in general. Now the builder has gotten worse. You (or at least my old eyes can't) see if number fields are set for decimal places any longer just by glancing.
Take a look at this screenshot. One field is set for decimal places.
