Resize-able field on the goal page

Summary

Long Description or other fields

Content

Hi, 

Do you have any idea or knowledge, whether there is any field (beside the description) on the goal plan that can resize?
I would like have an additional field which is appearing in the same way as the description field (the key point, this field should have the enlarging option).

Previously we used the comment field, but it has another look and no option for make the box larger. Now, I was trying to use the long description, but it has the same working as the comment field. 

Thanks,
Dora
