Use Display Templates when rendering results on SharePoint Home
At the top of the SharePoint Home page (_layouts/15/sharepoint.aspx) is a search box. The items shown as a result of using that search box do not respect any configured Display Templates.

I am considering this a super important feature and I do not understand why this topic has so few attention.
Currently Custom Display Templates are only supported on the Site Collection which they are configured on. It is a pitty we are not able to define "global" Display Templates that are also used by the Office 365 default Pages (like SharePoint Home)

This would be great - search templates in classic SharePoint worked very well - would be nice to see this in modern SharePoint Home Search.
