LIGHTROOM/ACR - Use icons for selecting standard white balance. Sunny, Cloudy, Tungsten, etc.
Instead of using a pull down for preset white balance. Add the basic icons for Sunny, Cloudy, Shady, Tungsten, etc. This will allow to quickly select the temp you want. Highlight icon when 'As Shot' uses a standard white balance. Double clicking 'WB:' before the icons would reset the white balance to 'As Shot'.
