I love this feature all the time to group my tabs, but I have two requests:

1) is there a way to group tabs by cookies and other info other than just a URL? I have two google accounts (work and personal), and when I tell my personal to own my personal Gmail and then open up my work Gmail account, it wants to assign it to my personal space.
2) Can this be better integrated with the address search tabs feature so that the results could be from any container-ed tab, not just that of the container to which the tab I'm searching belongs?

Keep up the excellent work!
