I use containers as a separation of work areas so that I can switch between work and entertainment so that unnecessary tabs don't distract me. Containers don't do that well!

1) I want the containers to be easier to hide. Right now the interface is complicated, there are a lot of clicks.
2) It's not clear why a hidden container drops me all the tabs in it if I add a new tab to the container. I just want to add a tab, not open 100 tabs I don't need!
3) I see the concept of containers as switching different desktops. So that they don't mix with each other unnecessarily.
4) Tabs outside of containers. There should be a setting that specifies what to do with these tabs: either hide them when any container is open, or leave them parallel to the container.
