Change wp-admin and/or wp-login.php urls with anything else

This suggestion could be added to Ultimate Branding plugin. Or maybe new plugin to think over

I'd love to be able to hide the "/wp-admin/" and "/wp-login.php" and change them to someting like /my-admin/ and "/my-login.php"

They are multiple pros to do that.
1) easier url to remember for our clients
2) Security issue. Hackers often attack wordpress. If they can not find the admin and login url, it is a little more difficult

What do you think about ?
Thanks
