implemented a system to track what portion of a document is affect by an editor action. Used that system to help solve extensive whitespace handling problems, ans also problems with caret placement in response to returns (this lattter fix for html editors only - plaintext coming later). Fixed numerous list bugs involving outdenting, unlisting, and splitting lists.
