This extension, which can be found in the Chrome Web Store, is a simple extension that has been developed with the aim of creating a new window when the last tab is closed.

There is an important requirement: you have to enable the setting "Continue running background apps when Chromium is closed".

This can be done by going to "Settings" - "Advanced" and enabling the "Continue running background apps when Chromium is closed" option.

The properties that can be applied to the new tab are the same as the properties of the closing tab.

However, this does not work correctly when the Chromium window is not maximized.

This extension only works if the Chromium window is maximized.

You will not be able to select the properties of the Chromium window from within this extension.
