I still didn’t download and tried any of these Beta versions, but I thought to pitch in with my two bits…
An immediate redo of any check with a change in the options is a mixed blessing. You sometimes what to change more than one. So the immediate response after just one change might be distracting or even irritating. Take for example the Visual Basic’s continuous, on-line syntax analysis: you start an edit on one line only to see another thing to be fixed on a second line. You leave the current line and suddenly a syntax error pops up and you have to acknowledge it. Irritating!
Just my thoughts…
