I really want to like this extension but despite existing for all these years, it doesn't even have support to add or modify URLs. It's absolutely ridiculous and shameful. This extension is absolutely worthless for the sites you want to partition out into their own containers, such as banking sites because if the URL subdomain changes even a little bit, it'll toss the website into a regular tab.

Since this is open source, I went to check and see if anybody else has complained about this and they have. There is even a contributor who has already coded this out, but despite the request being there for 2 YEARS nothing has come of it. This is a joke.
