Excellent, could use some work on the design side, but it functions perfectly.

Just what I want.
A little problem, I'm not sure whether I can use wildcard or regex in the domain list, hope can add instructions about it.

Feature Request: hope can add a option, let opening new tab without container for unmatched domain, cause for my case it's almost unnecessary, though maybe the default behavior is useful for somebody.

Great use! But as someone suggested, I wish there is a default/fallback option where any website not matching any domain would be opened in a default container.

This is a great extension. Manually changing the containers was a serious limitation for me. This perfectly isolates my work, banking and personal surfing.

It will be absolutely flawless even if you implement a very rudimentary wildcard support.

Something like (*.google.com) should work for:

maps.google.com
mail.google.com
plus.google.com

To limit the complexity, you need not support partial wildcards, like (m*.google.com) or wildcards in the suffix (example - google.* for google.in, google.com etc).

Good luck! :) Hope to see some sort of wildcard support in future updates.

Can you add wildcard support?
