Sure.

Don't make the description overly specific to the new tab page. Chrome Home is a
UI surface that features these items out of the context of a NTP

It would be nice if we could also track dismissals / removals from swipes.
Should that be a tracked separately from dismissal by context menu?

[dgn, 2017/04/24 14:06:38]

I think tracking what part of the UI is used for which result would be nice, so

[Galia, 2017/04/24 15:13:49]

Right, I'll do that, too.
