> And even Emacs doesn't allow for floating windows/dialogs, nor does it show text-mode scrollbars or windowing widgets.

However, the floating window had its downsides. They hid what was behind the window and modals, so if you started a dialog box and changed your mind about the text behind it, you have to close the dialog box, change the text and restart your dialog box.

Emacs and Vim avoid these problems by turning everything into a buffer. So all of your interactions with the editor are done through buffers which can be opened side by side.
