Helix is, but I don’t think Zed is? At least not by default. It has a command palette and multi-buffer, multi-cursor, but not visual/normal/nsert/etc AFAIK

I’ve used Mullvad for years, and from what I know, they store almost nothing – only your randomly generated account number. If you are paying using an anonymous method that’s even less to go on.
