Had really busy months and a little time off - in the meantime I found a nice solution to use templates in Crafts app. I build an action for Drafts which lets you setup and use template notes for Craft. Download the action in the action directory and start using templates now: https://actions.getdrafts.com/a/1re

If you have any questions or feedback, just reach out to me on twitter or in the Drafts forums
