In Scratch 2.0, I really like the fact that if you drop the block near the wall of blocks (in the left), It will alight pretty good. I use this feature in order to make my script more organize. But in scratch 3.0, It's not possible anymore. I start to stop visiting the site less than I used to be when scratch 2.0 still in the online editor. I hope that you will add this feature back. Thank you
