The TileLayout is a great way to show data in a dashboard, but lacks a dataSource to allow dynamic generation of them. I have had to create a custom extension that introduces a dataSource, which then utilises `widget.setOptions({ containers: items })`. But this puts too much reliance on custom code and is a worry that it will break between version upgrades. Also, editing one container doesn't allow the refreshing of one tile; I need to reset the whole lot using `setOptions`.

Adding, editing, resizing, and re-ordering are also difficult to implement for a tool that has huge potential.
