Say good-bay to the rainbow cursor
  CotEditor 4.3 improves the performance of syntax highlighting and file opening drastically. For example, the procedure that required a 2-minute rainbow cursor finishes now just in one second. Now you can open files of more than 100 MB in CotEditor without hesitation.
