Controller margins

Is there any way to adjust JCplayer controller alignment?
I tried margins, but controller section adjusted based on center position.
I want to add an extra button on the right side of controller (may be next of full screen button).
How I do that?

Thanks.

If you want to add the extra button inside the component then, that's not possible. However, JCPlayer is a fla based component, so you can easy do what you want by editing JCPlayer Assets from the library(Separators).

Do you have any plan to add margin left or margin right option?

I'm afraid not. The new version won't be fla based.
