I'm a zsh user with a slightly complicated configuration. Fish or something else more modern with sane defaults could lure me away some day.
I want to like helix. I've been using vim for twenty years. I suppose I have to put in some work to make the switch... no time and limited mental capacity (plus muscle memory).
I have looked at Zellij and decided I like my simple tmux workflow better (it's configured to behave like GNU screen because I have twenty years of muscle memory for that too).
Regarding Lazygit, I actually enjoy using standard git. I am pretty good at branches, rebasing, and other things.
