Emacs has first party support for these approach. Buffers are separate from the windows (aka panes) where they are displayed. And the latter are arranged in a tiling manner in frames (aka windows). The buffer themselves doesn't need to be tied to a file and you can use concept like narrowing to restrict the viewable part. In elisp, you will fine often the form feed ascii code (^L) which allows to define sections which can be restricted with the `narrow-to-page` command.

On my work laptop I usually have many emacs frames. One displaying a `term-mode` (terminal) buffer, another usually displaying some `compilation-mode` buffer (tests, lint) or `grep` results, two as active workspaces as I'm often dealing with different modules (one maybe the api and the other a UI component). I create other frames as I need them (like exploring another project or doing some git-fu with magit).
