I have few suggestions to put forward, which might help you to enhance in its next version.

1. Along with Image & Video Gallery, U can also add Music gallery with a custom player skins to be placed at custom position.

2. It will be good if you give us a detailed video tutorials on using all features rather than a basic one.

3. Also include few Banner carousels for the users to choose with. Also provide an option to add custom jquery in banners and Mouse rollover on thumbnails.

4. Also u can try developing a Software for creating Apps say Incomedia App X5 Evolution.
