One question @ludeeus . The single-card in tracker.json requirement for this ... do you consider that a missing feature that you intend to fix? Based on #22 it seems like the editor should be its own card, meaning I'm likely to end up with 2 entries in tracker.json and suddenly break updates for people using this (way better) install method.

Should not be an issue as long as the name of it will be simple-thermostat-editor.
Near the bottom of the link I added you will see that it tries to fetch 3 files from the repo.

When all that is taken care of, it will start to download the card file(s). It will try to get these:

- custom-card-name.js
- custom-card-name.lib.js
 -custom-card-name-editor.js

I think that should hold for most cards, so I'm currently not considering it as a missing feature :)

I did miss that part yes! That makes it clear :) I think this is a fair convention to expect.
