Simple aggregation | Drupal.org
A simple aggregation module for Drupal 7 that reduces the number of aggregated files by: Moving the “System” aggregate to the start of the “Module” aggregate. Preventing modules from adding CSS files with the "screen" media type. (They are converted to "all".) Preventing external CSS files, inline CSS, IE conditional CSS files, or different media type CSS files from splitting aggregate files due to the order they were added to the system. Preventing empty aggregate files from being loaded. Project goal To be a configuration-less aggregation option that works better than core.
