Hello Jacquee and Kathy,
I see your time slots have filled up. It would have been nice to discuss the panel functionality with you. In lieu of that, here is how I use the panels/trays in both SU and LO.
I find this configuration works very well for me. I work on a 45" 3440x1440 curved display. I like to work with LO and SU side by side with the main working spaces toward the center, thus SU’s trays are on the right while LO’s trays are on the Left.
I also group the trays into function groups that make sense for my workflow.
I don’t like to take time expanding/contracting panels, nor do I like to use the scroll bars to find what I’m looking for. I find keeping a few related panels fully expanded in 4 trays as a fairly fast way to work. This keeps items I’m looking for in around the same spot, versus having to scan up and down with the scroll or expanding panels.
I occasionally use the pin/unpin feature of the trays when I’m on a small laptop screen or doing a presentation, otherwise I rarely use that feature.
