 ## Current plans
 
-- [ ] Allow the user to choose different options (Changing pin, name, etc)
+- [x] Allow the user to choose different options (Changing pin, name, etc)
 - [ ] Make a prototype. Allow variables to be stored & displayed.
 - [ ] Intergrate it into XML. For now, only allow PIN & money to be changed.
 - [ ] Add a way to create new users.
