This is a window test. Just know that this is still in development. I has features like closing, opening, making the window fullscreen (Which may not work) It isn't much. It could be a little buggy, So, Tell me if there is any bugs (I would also like if you post here: https://scratch.mit.edu/discuss/topic/851008/?page=1#post-8826207) UPDATE: 0.2 (Nov 18): I fixed the red and green buttons as they weren't really working because i added the if touching mouse-pointer block. Thanks to @-GreenWonder- and @knacktick for the help. 0.2.1 (Nov 18): I removed the green button because it was too much as the problems couldn't be solved.
