I get your point. I messed with eshell for a while, then used vterm. In the end I just hard wired a swaywm key to a scratch terminal wihch toggles an alacritty instance. I can copy and paste in it fine : in short I find it easier to do “terminal shell things” in a “real terminal” but I can see why others prefer to stay inside emacs. Occasioanlly I’ll use a terminal inside emacs via projectile as its quick to open a terminal at your current project location.
