Containers have become an essential part of my workflow for managing multiple accounts, improving privacy, and isolating contexts like work/home life in the same browser. Admittedly, containers will probably never be a perfect solution (e.g. I still don't have a way to ensure that my Google drive link from the electron Slack app opens in the right container for the right Google account)... but Multi-Account containers extension smooths out most of the rough spots by enabling some sites to always stay in a container, and adding convenient keyboard commands and context menu options to open sites in a specific container. It doesn't seem like this extension provides a shortcut for "new tab in the same container", but I'd like to see that added. For now, I have installed another extension that sets that feature to Alt + C. Great extension;, though! I'd love to see it on android.
