Label User Manual pages with HMI system
In the user manual, on every component page, Put a BIG "Perspective" or "Vision" label at the top of the page. Then I can avoid reading half the page before I find out is not for the HMI system I am using. (or the report module!)
Related: if a similar component exists in the other HMI system, put some links near the top of the page.
Which pages are you looking at? The 8.0 and 8.1 manual already state their visualization system on the title of the page.
