Whats the correct way for users logged in? I know the style chooser is there for a reason but I'm working on something else that may need manual links to other styles logged in/out.
This is entirely intentional - anything that changes the user state shouldn't be available via GET, unless it's protected by a user-specific token. It's effectively a CSRF issue.
That may have been a bit tongue in cheek. I just funded three big add-ons (IMO). Trophy Promotions, Mass Alerts, and Duplicate IP check for multiple users.
