Since @Jopyth hasn't responded to issues or PRs lately, I suggest using my fork: https://github.com/KristjanESPERANTO/MMM-Buttons 🙂
I managed to get rid of the dependencies. This means you no longer need to run npm install (which was also necessary after every MagicMirror update in order to run electron-rebuild).
In addition to many minor changes, I have also added logging for the frontend, which is very helpful for testing and debugging.
Feedback is very welcome.
@Jopyth, I suggest that you mark this repo as archived. Thanks for this cool module!
