How to reduce the size of the System Folder panel?

I am in the process of migrating from a MacPro (2013) to a Mac Mini Pro M2 running Ventura. Capture One 23 functions well, but I have a problem with the System Folder panel on the left side of the screen. Because it contains all of my image folders from many years of photography, the panel takes up the entire side of the screen and thus requires much scrolling to see things like Filters, Keywords etc. There does not seem to be any way to reduce the size/height of the System Folder panel, as there was on my MacPro. Does anyone know how this might be done?
