Thank you for reaching out to us.
Simply visit the website you’d like to add, open the sidebar, click the

yeah but this is a shortcut to the website, im asking if theres a floating window or any way to duplicate the screen so i can access two websites at same time
This is not something available within the browser at this time. You can only do this by using the built in features of OS for split screen and all.
oh okay, brave should add this feature because its very interesting, but thank you anyways!
