Align notification bar with the navigation bar

[sferra]

This fixes the issue of the notification bar convering the "collapse" button of the navigation bar. See #904

Thanks for your support @sferra ! Could you attach the image?

I just noticed that the notification is not centered. I'll try to fix that too.

The notification is now centered in the notification bar.

Thanks so much @sferra ! Your PRs are very helpful.

1, Could you fix layout at expand mode?

2, How do you think about bringing the Notification area to the right? I think this layout looks better.

Thanks!

@kazup01 thanks for testing. i would prefer to address the "notification" position with a separate pull request if that's okay with you. the notification position might be an improvement but it's not related to the actual bug of not being able to toggle the navigation bar.
