Ever been making a project and wanted a simpler way to make an And block chain? Well, here's the solution! The Comma Block would work like an And block, but when you put something into the second blank spot, it adds another! This would help you be able to do stuff like 'If <Touching () and Mouse Down and (Variable)=() and <Not Touching ()>> then'(example) without the extra And blocks needed, to help optimise your projects.
Note that the difference is that the Comma block would be used for 3 or more things whereas the And block currently only allows 2 without extra And blocks.
