It would be great if the data viewer supported tooltips for large objects. Currently, when looking at the data viewer, if the cell contains a large object, I get a message saying the field is too large to be displayed which is understandable. My standard workaround is to add a tooltip to the mark with a signal of datum so I can see the details of the object like in my second screenshot. It would be really useful if instead of displaying the existing tooltip stating that the field is too large to display, we could replace or add to it the tooltip that shows when you hover over a mark.
