1. Добавлена возможность быстрой подстановки слов на латинице по нажатию Alt+RIGHT. Возможность включается настройкой "Use word hints". Список слов составляется при загрузке запроса и по мере ввода новых слов. 2. Добавлена возможность заменять при выполнении запроса переменные вида $1, $2, ... или :variableName1 на пользовательские значения введённые в диалоге. Пока можно заменять переменные в запросах select,update,delete,insert. Перед отправкой запроса на сервер переменные заменяются простой текстовой заменой. Запрос который выполнен на сервере можно посмотреть на вкладке История. Возможность включается настройкой "Replace variables in a query". Выделить правой кнопкой выполненый запрос не получиться т.к. текст выполненого запроса и текст в редакторе будет отличаться.
