For the last 3 weeks I've been working on this project pretty much daily. I thought it would be quicker than what it has been but I kept thinking of new features or encountering problems that I hadn't thought of.
I'm happy with my MVP but my main concern is that people won't understand how the add-on is supposed to work.
I think I'm just going to submit my request to Google to get this published in the G-Suite and request feedback from any users.
