Basic usage:

Drupal 8 provide greater caching mechanism. For developer, one need to clear cache for changing any template or module file. In Drupal 7, there is theme suggestion option available in View. It is not available in Drupal 8 View. We require to do manage that configuration with manually configuration from services.yml. So, we have developed module for developer so theme developer can easily rectify theme and module developer can manage module easily by enabling "Enable theme" option and "Disabling cache during development" respectively.
