Tabs are fine as long as they represent workspaces instead of a one-to-one mapping to files or buffers. I think the browser tab metaphor does not work very well

Tabs are fine as long as they represent workspaces instead of a one-to-one mapping to files or buffers. I think the browser tab metaphor does not work very well in a text editor without some modification since you often want to do split layouts and I really don't like the messiness of multiple tab bars. I think Emacs still has the most advanced system for window management and the only thing it should do is maybe modernise the UI surrounding it a bit.
