This looks good to go now!

If you're making a widget please start the name with wid to make it easy to find!

( @bobrippling I guess we should add this to the PR merge check list? https://github.com/espruino/BangleApps/wiki/App-Contribution )

To clarify, the appid should start with wid. Not the user facing name.

Thanks, just pushed. We could also add it to sanitycheck.js, by checking if type is widget, making sure it has prefix "wid"

I think that's a good idea!

Just made a PR for it, #4309

Now that #4309 is merged in, shall we merge this in as well?
