The slide block is a block that makes the sprite slide smoothly, faster at first, then it slows and goes slides to the destination (it's hard to explain, just press the green flag). It would be useful for many things. One example would be to create a smooth animation for your logo.
It's really a pretty simple script, I made it in a few minutes. See this project by @MathMathMath: https://scratch.mit.edu/projects/100299243/ This project is my own idea but the link above explains how it does it. :)
