That's great feedback, thanks! And no, I haven't posted it anywhere else yet - I've been playing with the models coming out of this a bit, but the website needs a bit more polish too, I agree. Your suggestions sound really reasonable, I'll have a look at that!
And regarding leads - I'd be open for that! This has more been a fun side project, but if there'd be an actual market I'd find that very interesting. Let me look into the above and I'll get back!
