The chrome extension helps you to duplicate a current chrome tab adding an extra url (www.site.com/admin e.q.).
That's enough to duplicate chrome tab for sign in to your admin part of your sites. It's a chrome extension was built to help you sign in. It's a useful extension when you have to administrate a lot of sites. Without this extension, you need to duplicate a chrome tab and type in the new tab your admin URL. For example, you are an administrator, you have opened site www.site.com and you need to sign in to admin part to www.site.com/admin/. All you need to do is to add /admin/ in a field on the extension popup. Then you just click on an icon of "the duplicator tab" and click on your added link /admin/ e.q. The chrome will open a current tab with the extra URL www.site.com/admin/. I hope you love it.
