Zooming just a component, for example a card, is also super usable, but in some regard it's a thing of its own. It would be very smooth if one could hold ALT or whatever pressed, and just hover a component, and then you would see a zoomed in version of the component on a layer of its own above the table layer, without it zooming the rest of the table and just zoomming the component. Very good for reading, and also solves issue with having to "move in and move out with camera all the time".
