[Plugin: Super Smooth Scroll] Keep default scrollbar

Hi all,

I really love how I can scroll smoothly with this plugin, but I’d like to know if it’s possible to keep the default scrollbar instead of it automatically changing to the custom one?

I ask because when a page is loaded the default scrollbar appears for moment before changing to the custom one causing the page to jump slightly – is there a way to prevent that?

Is there an alternative plugin out there that might better suit my needs?

Any help is appreciated!
