@Toploftical Suggestion is a good idea and add repository of TAGS with explanations
One of the best features - unique (to my knowledge) - to Facer is the ability to see how actual watchfaces are made (if the creator allows it) and learn from those.
But this feature is underutilized because we have to hunt for watchfaces one by one to find those that we can learn from…
In the Facer Creator we already have links to the documentation which is very helpful but I would also add a link to browse and search watchfaces with this “how it works” feature enabled.
