It's not a reskinned if block, if it was, it would still go to the mouse THEN increment the variable, it's its own loop Why is this feature here yet unusable by normal standards??
Favorite this project if you think the 'while' block should become official, this isn't for the sake of fame, this is a legit petition, I want to know how many people want this, besides, it's ever-so-slightly more convenient to just have a while block than to put a 'not' into a 'repeat until' that it just might make more people go to Scratch!
