It is highly recommended to enable the picture-in-picture feature in Codex, which can launch multiple browser pages simultaneously in a picture-in-picture manner!

It no longer competes with you for control of the local computer, and at the same time greatly improves the operating efficiency of browser use.

The picture in the picture is a picture-in-picture screenshot of three browser pages that I opened at the same time.

It doesn’t affect my ability to type and tweet now.

It’s so useful!
