I also would love a better focus peaking..
option to change color.
or marking the peaking areas with zebra-stripes or checkers and therefore the highlights with dots or so instead ... would be much better.
Canons magic lantern is also a bit confusing here, because to me it seems very unlogical to use blinking dots to show in-focus or "high-contrast" areas...
They use the zebra-stripes for showing highlights..
Sony is very innovative here, it seems to inherit an algorithm in LV that finds the very contrasty "edges" and only marks those edges/lines yellow AFAIR.
Could be an additional feature to the next Q with EVF...
