A couple issues with banner

I like this plugin a lot but I have 2 minor issues…first, I have a hard time formatting the description text. If I just type it all in, the words split oddly at the end of the allowed space. I had to use non-breaking html spaces to help space the text properly. Is there anyway you can add WYSIWYG editing? Also, I have selected the banner to only show on the home page but it shows on every page!
