Unclear navigation for Settings Menu

[kroucis]

It is unclear how to dismiss the Settings menu after clicking on the gear icon in the bottom tray. The Settings menu takes up the whole window and provides no "x" button or similar to close it.

Clicking on my profile picture at the bottom dismisses the Settings menu, but pressing the back arrow button will open the Settings menu again.

Expectation: I would expect an "X" or "Close" button for the Settings menu, and for the back button to not consider the Settings menu as a navigation page.
