Feature request from chasteIT, posted on GitHub Sep 03, 2015
In Magento2, can we please get the ability to set default configurations of Configurable Products?
@tzyganu's Easylife Switcher that sets default configurations, keeps the selected options when other above them change. It also changes the product image or media block when options are changed -- among other cool stuff.
Also, Inchoo did a tutorial on autoselecting configurable product options, and Iceberg Commerce provided a Javascript method.
Lastly, pre-selecting default simple products would affect the Simple Configurable Products #335 undertaking.
Edit: This could be used in conjunction with layered navigation. See issue: Layered Navigation Filters Pre-Select Configurable Product Options #1784
