Layer Slideshow Ideas/Wishlist

Also, I feel there's a lot of potential in this program, but not a lot of options.

For Example:
- Undo Option
- Google Fonts
- Animation Control (speed, size, style, etc.)
- Removing/Adding Text Layers
- Removing/Adding Image Layers
- Shortcode Inserts like RSForms or Widgetkit
- More Sizing control

Is there a roadmap? I really like where this is going and think it would be great to see more of.
