First, thank you for the software, I really like it.
Can I kindly ask me to help regarding the following requests ?
1. When an invalid IP is entered, I receive a 404 error, I want to show the error message inside the main web page, not in another 404 page. I don’t want the user to leave the initial interface.
2. Some translation text is missing like : Your IP Address , Geolocation for IP Address
3. I wish there was an easy way to insert scripts to head, body, footer etc, via the web interface.
4. What does the button with the text “Ip Check ?” do ? 
Many thanks in advance…
