Nobody gives anything, especially WD PRO, but I will give you this gift.
This is my first chore with WD PRO.
Of course you have to adapt it to your PB.
Thumbnail loads at startup, do a fade from layer 1 to layer 2 and layer charge on the clip that does not appear that is currently visible.
Maybe there is a better way to do it but it works
Until next time.
