Be able to choose Transparent Background in Color Control component

I have seen in the Color Control Component is possible to choose colors and change the setting to allow the load of images, and is allowed to have the built in images with transparency or load a image with transparent background, BUT there is no way to tell FF to fill the background with a plain transparent background

Please, Would be possible to add this option of Transparent Background (Alpha) to the color control ?

In the color control help is put

Quote
The alpha channel of Color cannot be changed and is always set to 100% (to modify the alpha channel, use the Set Alpha component).

Why must the creator of the filter need to use the Set Alpha if you want to have the choice of giving the option to have an Alpha Channel as background (Transparent Background) OR if it is not the author, a filter must be changed to make this and then the author LOOSES all the usage rank and any kind of rewards.

I suggest adding this as shown below
