I'm someone who went from playing on a browser to here.

The NUMBER ONE thing that bothers me is how there's no keyboard shortcut for switching tabs.

Make it the same as browsers please-> Ctrl + Tab to switch tabs. It should be easy to implement.

People running multiple accounts NEEED THIS

Another thing that i'm seeing is that in the login screen, we can't use Ctrl + a to select all text. That should be a simple fix too.
