Move the preview button away from notification area
On macOS, notifications come from right to left right below the menu bar on the top right. This means that whenever you get a notification, the preview button and the surrounding interactions are covered.
It's of course frustrating that you ever so often need to close notifications to interact with the preview button. And what's really frustrating is all those times when you are about to click on the preview button, but a notification suddenly gets inbetween and you accidentally open upp Messages, Calendar, Slack or any other app that you got a notification from instead of previewing your design.
There's got to be a better way to place those interactions.
