I would like to see more responsiveness in the grid.  I believe what i understand to be known as stacking could be achieved by additions to the media operator on columns.  Thus we could have media=".col-sm-12 col-md-6 col-lg-4 col-xl-3".  The underlying code could then use media queries and where the column will not fit on the device without the ugly scroll bar it would wrap the columns in a kendo-grid-span-column directive giving a card-like effect on smaller devices.  Of course this may need some columns to be hidden on smaller devices so we could also use the [hidden] directive like so: [hidden]="sm".  The next thing you would have to think about would be what to do with column headers when a row is stacked and, again, we could use the [hidden]="sm".
