User Menu

### Your use case

#### What would you like to do?
1. Make icons white.
2. Reduce icon size.
3. change full divider to an inset divider.
- Or no divider line at all.
4. Add copy username
5. Add click avatar and/or display name to open account settings.
#### Why would you like to do it?
1. Grey icon + white text isn't seen in other menus (dark mode).
2. Softens the divide to make the menu look like one whole.

### Have you considered any alternatives?
change the icons on similar level menus to grey.

### Additional context

I would propose using inset dividers in all pop up menus.
