这个 Pseudo Effect Maker 脚本可以简单高效的将多个表达式随意组合成自己需要控制的操作，
A pseudo effect is also known as a ‘custom expression control’. After Effects has several expression controls built in, however, they are all individually separated. This means that if you need to use multiple controls for your project, each one will have to be added separately, which can quickly get messy and unorganized.A pseudo effect allows you to create a custom group of controls that can be named and organized however you want and make your expression controls easier to work with and look more like built in effects.
