I’ve made a pack to send messages to Tasker using the AutoRemote plugin. I’ve used this to get a more native ‘app’ experience for my doc. For example I have a grocery list doc that when I move items from list to cart, logs the GPS coordinates (that the pack gets from my phone using tasker)
Using this I can map food sections and product locations in my grocery store while shopping, calculate a short path and sort my grocery list to follow a corresponding route.
See the doc below on details for everything you need to setup to do such a thing.
