I love the direction the new Grid layout is going! I’ve begun using it in my work for certain cases, but I anticipate I’ll use it for almost everything whenever a few of the upcoming features are released.
One thing I’ve run into repeatedly is when trying to adjust a grid, I can’t seem to find the track size dots. From the tutorials and Grid playground file, I know the dots are supposed to show up when hovering over a cell.

I kept thinking I’d accidentally changed my view mode or hit some unknown hotkey, but I finally realized that the track dots only show up below a certain zoom level.

Now that I realize this, it seems clear that this behavior is by design. I only wanted to mention it because it confused me multiple times in the few weeks I’ve been using it, and I only noticed the zoom-level having an effect by accident.
Perhaps there’s a way to make it clearer that the dots show up when you zoom in, or I wonder whether the dots could just be shown all of the time?
