Double-click on develop sliders not working correctly in LrC 15
In all previous versions of LrC, double-clicking on a develop slider returned it to its global default value, which is zero for most sliders. In 15, it isn't working that way. It appears that it may be resetting to the value associated with the applied preset instead, which in about 99% of the cases where I do it means that it will have no effect at all. If this was an intentional change, I hate it, and the option to have it work the old way needs to be available in the Preferences menu. If it's a bug, please fix it.
