title: General questions about JHipster
body: <p>Sorry if this is not a place to ask these questions. But I just want to know if...</p>
  
  <ol>
  <li>Can JHipster go large scale applications? </li>
  <li>Is it possible to minimize the generation of codes especially with the UI part?</li>
  <li>Can I extend some RestController class that has been generated to. (Like a custom model class where in I get base64 string to write in a file)  </li>
  </ol>
  
  <p>Sorry again for asking, its just that I'm building a startup business and I want to know if these are all possible. I can't help but to get over excited on JHipster and I'm literally crossing my fingers now!</p>
  
  <p>Thanks guys!</p>
