Right margin when fixed widget

Hi

I’ve installed your plugin and I have a problem, it seems to extend the right margin of the widget for the fixed widget

Please check this video you’ll understand much better (there is also the audio on so you can listen to me explaining what is going on)

Btw is it the same plugin than Q2W3??? I had this one installed, removed it, installed yourt plugin, and the same exact option show up.

Thanks

Nicolas.
