I have the autosave plugin for CKEditor enabled and working, but I want to change from some of the default settings (specifically save detection selectors and autosave_delay) and can't get the settings to "stick". I have been editing ckeditor.config.js (in modules/patched/ckeditor/) and, while that's executing, the settings changes aren't making it to the editor instance running on the page. I've also hacked at ckeditor.utils.js because I was able to get closer to the actual instance but I know that isn't best practice and I'll regret it down the road.
Drupal7 fyi
