Currently if you reply to a thread, click on discard, then close the newly appeared prompt window by pressing the X you will loose the text instead of being able to keep writing.

The "x/close" button acts as if pressing Discard, when it would be more intuitive to act as Keep Writing.

It would be preferable to have the X button act as Keep Writing so that there is less chance to lose the text , and it would be more intuitive.
