1. Button positions:
Only right side. A crippling feature.
2. reset image to default:
once a custom image is set, it cannot be reset to default.
3. If content is long, it remains hidden.
(Solution: Add overflow: auto;
under "#sideoffer" section of "sideoffer.php") Although the content extends outside the container while scrolling. Probably it needs its own div.
Worth 5 stars, if these changes are introduced
