Special handling of closing the last tab - is it intended?

[wanderor]

This app currently handles the closing of the last tab specially.

When closing a tab, the typical behaviors are:

• Ask user for confirmation if the settings say so.
• After the tab is closed, it is gone. If I quite the app and then reopen it, that tab will not show up again.

However, when closing the last tab, the behavior is:

• No user confirmation is requested, even if the settings say so.
• If I quite the app and then reopen it, the closed tab comes back.

Is this intended or is it a bug? If it is a bug, I can submit a fix.
