SideBar Margin Swap just like in mergely editor demo

[Srinath VS]

Hello,

First off thanks for this awesome editor. I love mergely,

I have two questions.

1. I want to bring the rhs side bar to center. You have provided an option to swap right margin to center in https://editor.mergely.com/. How to do that using mergely?.

2. How to set an option dynamically via function?(like clicking a button). I want a button that toggles ignore white space option but i couldn't find any docs on how to set an option to mergely. If something is there please share some links.
Please advise,

Thanks,
Srinath
