Roll the circular avatar in the header into Unraid OS itself and display the current username next to it in place of the hamburger menu

This is following on from https://forums.unraid.net/topic/190845-move-the-logout-icon-in-the-header-to-the-right-most-position/ and https://forums.unraid.net/topic/190846-move-sign-out-of-unraidnet-into-settings-for-unraid-connect/ :

The hamburger menu in the header is very odd in its placement and that it's for Unraid Connect is baffling as a design choice.

The circular avatar next to it should actually be rolled into Unraid OS itself, and the name of the current user should be displayed next to it. When clicking it, you should get a drop-down menu, as is pretty standard on most UIs with social media, apps et al.

Unraid Connect as a plugin should instead append functionality to the menu, if appropriate. However, I would argue that a Sign out of Unraid.net menu option is absolutely redundant and it's odd to have been implemented there in the first place and not in Settings in the Unraid OS section. Microsoft and Apple don't have Sign out of OneDrive in the Windows Start menu, but they do have OneDrive info (though I wish it could be toggled as I use Nextcloud for everything):
