I really wish magic wormhole worked conveniently on windows without obliging me to install python and pip and such. It's my go-to when sftp isn't an option, but for sftp not to be an option almost always means that one of the computers I'm trying to transfer between is a windows box.
Wormhole requirement: "the URL of a publicly-available Rendezvous Server"
This means its not a self-sovereign system, like Bittorrent, GIT, and Bitcoin. Its no different then a central Napster server, the one that got dragged into court on November 1999. Scientists are still working on creating self-sovereign peer-to-peer systems. Its hard, but we're going to solve it in coming years.

First time I hear about Magic Whateverâ„¢. Any modern download tool needs to be embedded into browsers and mobile OSes for it to have any chance these days.
I haven't seen any regular user use a separate download tool or a download manager for a decade or more.
Except for BitTorrent clients, but those aren't targeted at 1:1, of course :-)
