If the window is like this, it would be really great if the buttons would automatically go into a second or third line and so on. This would allow for an even more compact window.
Bonus for real fancy: Make it possible to narrow down the window to basically the width of the image and have the icons in a vertical row. Distance to the object and info like Sov Node ID could be comfortably below the image, but name of the object would be in a tooltip.
