Push Notifications Prompts break the back button. Many times I hit a search result on Google, find the page is irrelevant but I can't go back. That's because the page has prompted a push notification. I can't scroll either. It blocks the whole UI. That's very disruptive.
Second, while Postman is wonderful, Chrome's network tab is the super convenient. A very small change to allow replay requests to work via a keyboard shortcut would make a significant impact on the dev cycle. The use-case is to modify the server code then replay the request, rinse, repeat. The alternative is to copy-as-curl or proxy via postman, etc.
