I discovered that the plugins "Summernote Editor" and "Additional Contents" call jQuery (3.4.1). After installing both plugins and logging into CMS there are two jQuery libraries loaded. I tried to add a language pack to "Summernote Editor" - without success. I tried to use jQuery with "materialize.js" - no luck.
Sweet Bloody Mary, wouldn't it be worth doing some sort of cleanup with this?

I think it would be great. These plugin dependencies on libraries make a terrible mess (!).
Just to mention that the "Summernote Editor" itself requires 5 javascript and 3 stylesheets ... Holy Putin (!).
P.S. I discovered that "Simple Blog" plugin call further jQuery library v. 1.12.4 ... Holy Trump (!).
