Upload Wizard Campaign custom field length should be adequate. Now when maxLength is set to a high value it is extremely uncomfortable to put a lot of text into a tiny input type="text" field.
It should be solved by either of ways like:

• When the text input into a text field is longer than the default field width it should became longer and turn into multiline textarea on reaching end of the window.
• There should be a way to manually set its type to a textarea in the very campaign page
• It should be rendered as a textarea to begin with if maxLength is longer than some not very big value

(the list of possible solutions is not full and any other could be applied)
