Very good, but needs DaVinci inventions section

A very good high res collection of this great master, but needs to be "complete" as the description says. Very good but no invention sketches.

One thing though that I would love to see in a future update, is a section devoted to his machine sketches such as his ornithopter and other visionary stuff. I was kind of hoping that would be there when I initially bought the app, but coding this stuff is demanding and the app is excellent from the get go... I am patient also.... Bravo to the educational developers of todays technology!
