I want to like it, but its really buggy

I've been trying out the galleries this week and I love that you can upload raw media. The layout options for sections are great, but the controls seem really buggy. The up and down arrows for reordering sections seem to move sections to random spots on the page rather than up or down one position. When moving a photo from one section to another, not only does it not move there, but a duplicate asset appears in the original section. Then when you delete the duplicate, it deletes both assets. I think the ideas are good, but the implementation just needs some bug fixes. Thank you!
