Change loading indicator in Vaadin 8

Hi all,

I’ve tried to change the default loading indicator in Valo in order to match the look of other applications:

Show a centered spinning wheel and ‘disable’ (grey background/curtain) the application while loading.

It seems that for Vaadin 10 this is documented, but unfortunately not for Vaadin 8. Is there any documentation available regarding loading indicator for Vaadin 8? The loading bar on top is not really user friendly (IMHO).

Thanks in advance
