I have prepared an editor for the Zeus_MM.eng file. You will only have to change the text, the program will make the rest of the changes for you.
In this version, unlike the previous one, the following bugs are fixed:
1. If you open a file and move to any cell except the first, and then open a new file, then in the new file the cell that was active in the previous file will become empty (it is not counted from the file).
