Hi,
@patrick_digan pointed out to me today that in my ignorance I thought that the "On Success - Show Results to User" option in Interface Designer did something on Alteryx Gallery, like it does when run locally. I tried to prove him wrong (I've been manually checking off what outputs I want since day 1! How could it not have been doing anything?!) and failed miserably. As far as we can tell, this functionality is simply non-existent within Gallery.
Please add this functionality so that we can suppress files (without reverting to hacky tricks like changing the output location so the Gallery can't see the output) with a simple check box.
Link to my shame, where I very openly explained exactly how I thought I had been solving this problem the whole time, and how after testing and review, it looks like I hadn't done anything with this configuration.
All these check boxes... and they don't change anything!
