I never really set up a function for it, but what I usually do is in a new vim instance, I'll run the :term command, press ctrl-w o to make it the only window and then run a nested vim instance in that term window (typically one instance per vim tab). I'll open new terminals by running :tab :term. Basically, I'm using one instance of vim as a session manager to run other programs in, including vim itself. You can pass ctrl-w to a nested vim instance by pressing ctrl-w .
