Hello,
I'm back.
Always a worry.
I want to increase the number of displays
No matter how I modify slotMaxHeight nothing
I tried
in week : slotMaxHeight: "240px",
in month : slotMaxHeight:"150px",
in locale : slotMaxHeight: "150px",

What value to use?
Does slotCount: 3 have anything to do with the number of displays?
