Oh man, I hear you, most of this stuff is really random. your app was pretty neat though

I only tried your app on phone but it looks like you can't tap and add or drag things around. You always need to edit the numbers. Maybe the UX/UI could use some love?

Yeah. Click and drag is tricky in 3D, but I should add it to the 2D and list views though. I stopped working on it due to lack of any interest. I use it myself though.
