Left panel adjustable width

Nexus 2023.4.6.0 on Fedora, MacOS.

Adjusting the width of the entire left panel as well as individual column widths, while a stationXML is open, is a useful feature that has been present in earlier versions. It's useful because it helps with looking at the left panel by just scrolling instead of scrolling and hovering for details. In this version the individual columns can be adjusted before I open a stationXML, but not after. I cannot adjust the overall width of the left panel (the double horizontal arrow appears, but nothing happens when I click and drag), and dragging Nexus to a larger size only affects the right hand panel size.

I would describe this as not critical, but a useful feature if it can be restored without breaking anything. If the left panel overall width can no longer be adjusted, then I'd like to ask the apparent ability to do so no longer appears since trying to do that is frustrating.
