Needs some improvements

I love the app. Im only giving four stars because I wish the themes were customizable. Sometimes I like the look of a theme but the wording is inappropriate (like happy Birthday, etc). Also a big issue Ive been having lately is when I use the preloaded music in the app Facebook deletes the video because of copyright infringement. I thought the music would be royalty free. Maybe this is a Facebook problem but it is annoying. Im hoping that the creators of this app take these suggestions to heart.
