Use different screens wisely Before starting to create another screen, first you should think about is it really necessary?

[F/OS] - Dynamic Components Extension (for every component) 2.3.0

Dynamic Components Extension that supports every component in your AI2 distribution, instead of having pre-defined components. I thought about making a full method to create all dynamic components without creating different blocks for every component because it would be useless. So I was trying to find a proper solution for a long time. And here it is! The minimum required API version for this extension is 1 . It basically uses Java’s Reflection feature, so this allows you to create …

And to reuse the components multiple times.
