When I carry something in my right hand I am not able to tap the button to dismiss the notification. When I want to see what time it is, the notification time display on top is too small to be visible when notification is on, and very often I need to know the time precisely then 
If I could simply shake the notifications away it would be great. Alternatively if we could set the size of the time with notification on display that would be alternative solution.
+1. This would be an awesome feature! We’d have to make sure it’s a real shake and not just walking/bumping around for an accidental dismissal!
Actually there is an option to set the size of the time in the notification screen:
Settings → Notifications → Status Bar
there you can set it to “Big & Bold”, which is definitely better but imho not enough yet..
I’d like it better if it would be split screen with the watchface like the calendar reminders 
you could then tap the notification or press the center button to open the notification in full screen 
For example like timeline event view. That would help as well. But. It would require button press to show the content of the notification. Which would sometimes be annoying as well.
Thanks for the big and bold setting. I’ll try that
