I think there will always be a (large?) proportion of people that don’t read instructions before trying something, be that a new phone, TV or application. Part of the difficulty you face here here is that, in Drafts actions, we are so used to just downloading the action/group and it being ready to use.
Perhaps you could have the set-up action in an action group of its own at the very top of the list and name the action TAD-Setup/Refresh - RUN FIRST or something of that ilk?
Otherwise, I can’t think of a way to get the message more seen.
Just quick ideas off the top of my head. I don’t know how plausible any of them are.
Thanks for writing and publishing the suite. I have only used a very small percentage of it, but that is expanding as I get to know it. It is a fantastic and useful resource.
