> - New tabs do not inherit current container

Middle-clicking or Ctrl+clicking the New Tab button does inherit the current container. It also opens the new tab to the right of the current tab instead of at the far right of the tab strip. These actions are one in the same, so any extension that opens a tab to the right of the current tab (like Always Right or All Tabs Helper) also make the tab inherit the current container.

It's strange that such a useful feature is barely advertised at all in the UI, but it's there.

But your other criticisms of using containers as profiles are spot-on.
