Create "Add Text Box" in front-end

It doesn't make sense for a customer to have to hit "enter" at the end of each line if they are pasting a paragraph of text onto the document. When using this tool to build a brochure for example, the users need the ability to insert a text box on the front end so their text is constrained to that box and no need to "return" each line. The work is already done on the back-end so I am sure it's as simple as adding a button on the front end.
