Don't close window when opening a link

First off, really great plugin. I just wanted to suggest a small feature where when you click on a link it doesn't close the StreetPass popup window. This would allow for the user to open multiple links at once in several tabs and filter through them at once. Thanks :D

Also, it'd be great if the plugin remembers the location of the scrollbar.
