Remove the Reset button.

[bfabio]

Pressing the reset button is the most destructive action the user
can take but, despite that

• the expected result when pressed is not clear (clear all the fields
  in the current tab? Remove the current tab? Clear all the tabs? Remove
  all the tabs?)
• it doesn't ask for confirmation
• it's incredibly prominent (right next to the most used button)

Removing the language tabs can still be achieved more intuitively
by pressing the tab's close button.

Agree this point of view, actually it adds only confusion, it is not clear what is the real purpose and it is too close to the Generate button.
@libremente what do you think?

I'd start by inserting a message asking for confirmation when the Reset button is pressed. We can have a similar message to the one displayed when the X next to the language tab is clicked. I would not remove it for now.

@libremente we need to address this asap.
