<p>I know this probably goes against your overall vision for the project, and it would require a lot of reprogramming, so feel free to turn down this suggesion, but...</p>
<p>What if you made your song editor a bit more like a word processor? You could have a "Master Page" where the theme could be set up (and still changed "on-the-fly" in the Theme Manager). This master page could use a slide-shaped "page", which can be manually formatted to fit the screen dimensions (for example, 4:3 or 16:9, or any ratio the user wants). You could include a button to automatically add copyright info to the slide according to theme, if desired (or allow the user to enter it manually if the button is not activated). You could insert a master background image (or video loop?) in this page. You could insert a place-holding "shape" either by standard shapes (circles or rectangles of any size) or free-hand-drawn shapes which correspond to sections of the master background image. The words automatically format themselves outside of this shape, allowing you to have slide text curve around the outside edge of a globe, for example.</p>
<p>Within the text of the individual slide pages, you could use varying fonts, font sizes, and font colors (so, for example, the user could add a large title and hymn number at the top of the first slide if necessary). You could include a spell-check. You could even maybe add clip art to create sermon slides or announcement slides.</p>
<p>As I said, just a suggestion that I think would dramatically improve the program - if not for v.2, maybe in future versions.</p>
