Having the loader on every single page feels a bit weird in the navigation flow. But we still like for the initial site load. Is there any way to have it only on the initial load and not after further ajax calls ? 
We've tried disabling ajax calls in general settings with no success; it removed the preloader entierly.

Or maybe just on the home page.

Hello, 

Yes, I have tried with that setting on and off.

When on, the loader is on every page. If off, it is never shown.
