First of all, thank you very much for your awesome software. I really love Better WP Security. In particularly the "Login limit" function is really useful.
However, I would like to make a suggestion. It would be great if one could specify that IPs/Hosts that try to log-in as the "Admin" user are banned immediately and not only after X bad attempts. Namely, I removed the Admin user for security reasons. This means, anybody who tries to log-in as Admin, undoubtedly must be a "bad guy".
