a few questions before buying

 Hello,

the plugin seems really powerful but I have a few questions before buying it.

first, I tried to reproduce the configuration used on your demo but did not get there.

I would like to be sure to reproduce it because it is this type of layout that interests me.
Second, with this layout is it possible to change the color of a pre-defined image on the product? by selecting the colors in the right menus.

is it possible to prevent the user from leaving the defined frame?

And finally, is it possible to force the client to change the color of several elements at the same time (for example a text and an image)

is the main plugin enough to realize all this or is it necessary to add more?

Thank you in advance for your answers
