(n)vim can also do this, if you've set up an ssh alias in your ssh config for your multi-hop destination you just list it where the hostname would go. e.g.

nvim scp://remotemachine/.config/emacs/init.el

For the same reason you can use sshfs, sftp, and rsync with multi-hop. Gotta love openssh!

It's a very different experience:

- I already have tmux launched, if ssh drops – I can continue

- I don't have to match windows to ssh sessions -- just have them in my tmux
