Can you create an input field in the mybb installation process, that auto renames the admin folder, to whatever name the admin wants . It will be great to have the option in acp aswell. So whenever an admin feels like changing his acp location, he can do it with ease.
What's the point of this?
Get off you lazy butt and do it manually, there are some people that are not tech savey and dont even know where the admin panel is, best to leave it default.
I feel it'd be too much of a security issue to be able to edit your admin folder in the Admin CP. Not to also mention if you screw up you're having to edit both the mybb_settings table and inc/settings.php.
