Reorganize the UI: move the text editor into the file manager, on a new menu called "Create new" where users can create a folder or a file.
toolsGUI: implement functionality on the System Information screen, for displaying the history of user information registered on the System menu, including username, organization and password.
Yes, the OS keeps an internal history of this information. Don't ask me why it did this, but now it's at least useful (if someone steals your calculator and changes the user info, you'll still be able to prove it is yours, by looking at the history).
Utilities now also replaces the "Password" add-in, at least for its most popular use. Should I implement functionality for reading the password of Casio Basic programs, too?
