Safari Extension Develooper For SEO Plugin

I need to have developed a Safari extension that can show the following information by clicking an icon on the top bar of the Safari browser. 1. Redirect trace - if I click a URL, I want to see if the URL is jumping through one or more redirects, what redirect is being used (301, 302 etc.), and what different URLs are. 2. Noindex - icon that shows either green or red. Red if the URL is set to no index. 3. Nofollow - icon that shows either green or red. Red if the URL is to nofollow. 4. Canonical - icon that shows green, yellow or red. Green if canonical is self-referencing, yellow if no canonical is set and red if canonical is set to another URL. 5. Loadtime. You can find inspiration for the extension by looking at "Link Redirect Trace" for Chrome: [login to view URL]
