Very good!

Very good and really simple plugin, but some of standard functions of its library are not added to admin page.The lack of these settings causes various hard-to-fix problems due to partial incompatibility with other scripts and plugins.

I see a solution of this problem by adding the “advanced settings” or “advanced mode” fields in admin section, which could be globally specify values for some settings. For example:

parentEl: "body",
hideScrollbar: true,

Now I know how to do this by editing the .js file, but in case of updating the plugin, I will have to do all the settings again.
