Do you remember the MS-DOS Editor? Here is a poor imitation implemented with HTML, CSS and some JavaScript code.
You are able to edit this text, save it as a text file or print it (actually prints the entire web page, so it is not very useful). You can also upload files from your computer.
You can even learn how to cook some papas aliñás in gaditan style (check Help menu).
Thank you for reading this far.
Enjoy!
