I'd like to see this released in the current version, with all the intricate options added later through App updates (IE chrome, vendor products, garage details, options, etc). I think if you try to include vendor products they'll evolve them faster than you can add them and we'll never get to see this work. (Unless your master plan is to use the app as an advertising platform for their products?)
I'm 2 years into my build and early on I hoped I could use the app to figure out some of the build decisions, but it hasn't worked out. From the timelines it looks like a Bronco can be built faster than a Bronco builder app can be built. Not being critical, we all know life gets busy and projects expand in scope and scale.
Nonetheless, this looks like a great tool if it ever gets released.
Some of my favorite aviation apps started simple and developed along the way with user feedback.
