You can't use it without expending lots of time learning how to code. This plugin is for people who already know Javascript. By the way I don't agree with your «Construct is for no coding people».
This is even one of the slogans of Scirra so I have to disagree with you, C3 IS for no coding people. Just to be clear though. This addon is really good and expands the capabilities of C3, and that's great.
Dude, the fact that no-coding people is the Construct's target audience doesn't necessarily mean that this is it's only audience. There's a lot of people who know programming languages and use Construct in addition to Unity or even instead of Unity because Construct is so much better in some cases.
For example if you want to make a mini game for the internet media, you can't go with Unity. The minimal Unity build size for webGL is like 16MB. With Construct it's like 550KB.
I didn't say other people can't use it. I did say what you actually did right now, that's their audience. That's all.
