After a few hours with the Temporary Containers addon, I can reveal that this addon is *awesome*. It's just what the Containers system needed - I was already using an "Untrusted" container, but this is much better. Go use it!

@gwmngilfen finally! Tbh I still think the official container tabs addon should provide this funtionality, but this is still cool.
@grainloom agreed, but everything starts as an add-on or similar. Containers itself was a test-pilot program.
