as I'm loading the .js files from a CDN, editing the file is not an option, so would be great to have this as a feature!
Transition between items is removed on purpose. Reasons:
On slow machines transitions will not look smooth, especially if large images are used.
As progressive loading of images is enabled, it causes Paint each time some part loads. If animation will start before some image is fully loaded, there will be lags. Again, especially if images are big (1200px+)
Transition (especially “move”) distracts from the content. Most native image viewers don’t use any transition. As well as web photo-giants, like 500px, Flickr or Imgur.
In summary, there are no plans to add “move” transition between slides. “fade” – maybe, but currently there are more important features in todo list.
