Hmm. Do you mean that tab-bar-mode lets me have a full-screen Emacs (no UI elements whatsoever, as one does) and switch between window configs like if they were workspaces (which is what eyebrowse does)?
Yes exactly, by default it has a tab-bar UI element, but you just have to set tab-bar-show to nil and you can use it to switch between window configs without the UI.
If so, I might want to try it.
