Is there a way to disable the auto-expanding of resources clicked on

Hi Mike. I disagree. Why does the GUI no behaving like 99% of the rest of the programs out there.

If you click on the device it should just display its contents in the details side. If you click on the ">" arrow next to the device name then expand the device to show its sub-contents. 

This should be a toggle switch setting in your user specific profile. I'll open a feature request then on this.
