AstroDeluxe by Halloran has an Edit/Rectify function that works pretty well. Chart can be incremented by Date (Month, date, year) , Time (hour, minute, second) , Midheaven (Sign, degree, minute, second) and Ascendant (Sign, degree, minute, second). Any of those listed values can be incremented by a mouse click. The visible chart can be redrawn by a click and saved or not. It's about as intuitive as it could be.
