New Tab Page Walkthrough
Elliot Kirk I encourage the team to consider additional checkbox options under "Custom", such that the search box and news can be turned off too, resulting in blank NTP if desired with no extension necessary. It seems like this would be easy win vs. the seemingly popular opinion that NTP search/news elements can't be turned off in browsers because the vendor wants to advertise the search/news service. It also allows people to turn off what they consider to be distracting.
If the team doesn't agree, then it might be wise to ensure there's at least one NTP customization extension in the Edge extension store during beta to measure popularity and ensure tester coverage on that type of extension. (There are a number of extensions on Chrome Web Store that blank the NTP, these do appear to work in Edge Dev but we have to pop out to the Chrome Web Store to get them.)
