Edge should take a note from Firefox, on how it does it's new tab page.
In Firefox on the new page "Top Sites" can be customized, and pinned. This is a feature Edge really needs.
in Edge insider
also there are more improvements on the way,
"the ability to change the title of New Tab Page tiles is now expected in January"
Yea i'm aware you can add bookmarks, but you can't edit the icon, description or pin them on the page. Feature that is very much needed in my opinion
But good to hear they are improving it. :)
