From the Day One Weblog:
You will now have access to a Day One managed Templates Gallery, built right inside the app, that will be updated over time with new templates. You’ll also be able to create and save your own templates. Templates have been a requested feature by many faithful users and can help users overcome writers block, capture information quickly, track items/routines/changes over time, and help form a consistent journaling habit.
I’ve been been using a template for Day One that I setup and launch through Shortcuts. But having something like this built right in seems like a killer feature.
