[Eric Pettersen]

Hi Yuxin,

Yes, unfortunately the Contacts tool cannot be resized to be shorter/thinner than the combined size of the widgets it contains. It could probably be possible to make it resizable to be smaller with some additional work on the tool, but there are a lot of things to work on in ChimeraX and you are the first person to mention this as a problem. Perhaps if more people report this as a problem, then changing this could become more of a priority.
Thanks for reporting the issue though.
