Are you already able to horizontally scroll? Is there risk in your pr of not seeing the next notification?

[JFrankfurt]

Horizontal scroll functions already, though there's no visual affordance for it. The 35px offset is the same as the internal padding on these cards and it does allow enough space to see the next one on the screens I tested. (Pixel 3, Samsung something or other). Shoulda included a screenshot of the fix, but I'd already nuked my test data and was heading to bed.

I just tested w/ a few smaller devices and I'd actually in retrospect put this at a 20px margin instead, but it's better regardless. On the Moto G4 (not wide at all, only 360px) you almost can't see that there's a second.
