It's done. After weeks of work my ultimate dictionary is ready for use. It contains en.wiktionary.org and the missing entries from Webster's. Now you have a dictionary with old (i.e. quoth) and new (like AFAIK, RTFM...) entries. I hope it will help you in most situations.
You can find the final dictionary here in the first posting
