I'm somewhat new to ZSH; however, I'm using the DEV version on MacOS Big Sur and I do keep it up to date.
One issue I'm having is that my ZSH shell history seems to be unified -- that is, in different terminal windows I get shell history from separate sessions, which is not what I would expect (or desire). It makes finding recent commands a pain -- and I
wonder if there is a setting I've overlooked that will keep shell history in the current window isolated to that terminal session (until I exit, etc).
Thanks.
