Works when it works.
The problem 1 is, it opens all links from a container in the same container, you can not setup "default container" rules. (eg. google.com is in container A for a reason, but I want to open search results in default container so websites can be normal). Nor can not setup strict rules (eg. ONLY youtube.com is in container B, and all other sites will go back to normal)
The problem 2 is, no wildcard support. So if you want whole "Google" in a container, you have to setup rules like: drive.google.com, keep.google.com, image.google.com, maps.google.com etc.etc.etc. Instead of " *.google.com"
