Dear,

I have a columns of the Kanban with 5000 elements, it is very slow the scroller.
is there a flag to enable an buffered columns?
In the grid of Ext js there is a flag to enable the buffered store grid, so the grid is very fast.

Please help…

I didn't find the right solution from the Internet.
