Remove Loader and Scroll To Top

Hello, hope you are doing great ??

The plugin is great. It just does the job well, without any unnecessary bloat.

I just need help to change 2 things:

1.) The loading animation looks very outdated and does not sit well with the design of the website I’m working on.
How do I turn it off?
How do I load a custom loader from Codepen?
Maybe you can give me a code snippet, where I will add the markup.

2.) It should not scroll to top.
When someone is selecting filters, they want to stay in that place, until they have selected all of the filters they want.
If the page scrolls to top, then there is no difference from not using Ajax and reloading the whole page. The user experience is the same.
After pagination, it should scroll to top. But not while applying filters.
