Well,

- sometimes there's no info at all (eg: the solid booleans to name a few)

- there is no graphical header or footer, so they look like pages from my old Morris Minor 1000 owner's manual

- A modern font as used in the program itself .. Arial would do .. using bold text and the big icon as the title - just as the tools in the app do

- the diagrams are worse than awful .. see example attached.
... They need to be in colour (appropriate to the software)
... Black lines, green surfaces and blue solids would be appropriate
... Much much higher resolution
... They need to include click order (1, 2, 3 etc)

Ideally, they'd include a click-back button .. that would take you swiftly back to Concepts - though I don't know if this can be done
