Full controller / keyboard support

[smileyhead]

Describe the new feature: While you can already map controller buttons to gameplay actions, you cannot navigate menus with one, nor with a keyboard. I would suggest adding the ability to navigate the menus with the arrow keys and adding a focus signifier (pictured below) for clarity. Specifically for controllers, I would suggest switching out the header menus for radial menus (for quick access) (see Mario Maker 2 / GTA V) accessible via (using Xbox terminology) LT (game modes) and RT (osu!web tabs). Also, the ability to open the Settings and Notifications tabs with LB and RB.

Proposal designs of the feature:

Sounds like a very good and useful thing to implement, though highly depends on designing as we're lacking design for radial menus, and whether we should go with the proposed design for menu navigation. ping @arflyte

This is not an immediate concern. There are more pressing issues to attend to first.

I think it's immediate concern. Not support equal abandon using controller players.

Thanks for your input. No further input is required unless you are interested in implementing this.

sorry. I wrong place.

I think it is pretty necessary to navigate using a controller / arrow keys (keyboard)... Another option to display the selected menu button, why just not expand the select menu button, the same effect as hovering them
