On a daily basis some of the caches in Magento needs to be flushed. You should be able with the module config in admin to set what caches to be flushed and also what time of day it should be flushed.  The main reason is that some data is cached to hard by Magento and not flushed in time. This way we can assure that the cache is fresh in the morning. This module looks nice, but we need to be able to specify what caches should be flushed, like the FPC and block_cache only.
