Request: Open pages in a notebook tab
I think it is currently a bit confusing to find a way to jump between opened pages as it is "hidden" in a popover. Most IDEs I know (eclipse, vscode, netbeans, intellij) open new pages in new tabs, which could be a familiar behavior people know from browsers. Is this something you might consider to change, @chergert ?
(using GNOME Builder 3.32.4, sorry for opening this issue then if this has already been changed in a more recent version)
