Thanks, pietu. I really meant comments on developing other uses by you NSEs as i detailed above. But it may well be valid what you've said and 'normal' users just don't understand particularly those with limited EN or knowledge of terms. Regardless of whether it's 90% or 1% of normal users who can't follow it is arbitrary anyway, there will always be someone who doesn't follow what's happening because of their level of expertise or ability to learn. I had virtually no experience when i started to read and follow this thread over 3 years ago in Dec '11 [joined in Aug '11 - knew absolutely nothing, still knew practically nothing in that Dec, you see?]. At your much higher level of knowledge you've got your head around it in a few hours even with little English [by your own assessment ].

So, comments about further uses?
