Vfx added to shotcut

I would like to be added to Shotcut is Vfx basically I would like it where vfx we can have. Like fire lightning water etc in shotcut as vfx. I don’t want to keep have to download them as a green screen or black screen. And also I would like we can change the colour of the vfx.

Why would they need to add premade effects if you can just download/buy them from other sites? Also, why do you not wanna use Greenscreen effects? Just use the Chroma key filter to remove the green part.
