I'm using multiple dashboard.
How I can go one another with soft transition ?
You can chain several board together (as soon as you reach the last column of one board, you can go to the first one of the next board), but you cannot have a crossfade transition between them. Especially since it would be resource consuming to render 2 boards at the same time.
If it's a must-have, feel free to create
