It seems stable at this point. I've dropped using anything other than eshell & vterm in Emacs.

Can confirm—vterm is very stable now. I've ditched separate terminal applications and exclusively use Emacs+vterm.

Thanks

Is there a way to get fuzzy searchable history ala bash Ctrl+r?

Also I've noticed that if I use any emacs movement command (say jump to start of line) vterm looses internal sync and my edits edit the wrong text. Is that an issue specific to my config, or do you have it as well?

you should be able to leverage normal bash/zsh/&c. functionality.

the emacs movement issue I don't have, so perhaps that's a configuration issue.

(one perhaps useful tip: `vterm-copy-mode`, by default bound to C-c C-t, let's you navigate the buffer with normal emacs movement in order to copy)
