Probably they're using the "Sublime SFTP plugin" by wbond... I usually use nano on the remote server and sublime remotely via ssh with this plugin. But to be honest it is just for small tasks. 95% of the time we work in local servers with Vagrant/Docker (shared folder --> git push), since our deployments aren't that big.

I tried it, but I can't get used to navigating the filesystem with the command palette. It just looks weird IMO.

Yep, Sublime SFTP.
