Sure Metin,

You can try to enhance the existing classes behaviour. The cursor position sure might be confusing for the users, since from one point of view you should be able to position the cursor in the box, but by the requirement the input will only be done from the right position. You cannot avoid this conflict, however you could add some switch property(ies) to the class, so that some aspects of the class behaviour could be just turned on or off. The developer then will have a possibility to adjust the class behaviour to the different groups of users.
