It would be very helpful for larger documents if I had the ability to group/organize the parent pages in their panel. I am currently working on an urban planning document where each section of the master plan (parks, housing, wastewater, etc...) has a different colored footer and chapter page, so I have 8 different footer parent pages and 8 different chapter pages, on top of the 10 or so general layout parent pages I create for our urban planners to use as templates. Consequently, navigating the parents panel requires a LOT of scrolling. If I could just group all my footer parents in a folder and all my chapter parents in a folder, I could cut down the real estate they occupy in my panel.

I don't pretend to understand software development, but I suspect this would be a pretty straightforward feature to implement, right?
