For me, the folder size is "just right", although I agree it should be adjustable. When looking at a folder of a dozen maps, having a legible thumbnail can be very helpful in finding the right one. However, the top is really inefficient of space. I use a desktop with a big screen, and it still feels wasteful. I'd hate to be using it on a small laptop or similar. As @TheRollinOne noted, merging the seach field into the line above it would be cleaner. And there's no need for the "My Pages" title (note: I'm not talking about the "All page" breadcrumb, but the title at the top. I do like the upper-right close "x" on that line, but the line could retain it and be much smaller without the unnecessary title; and we can see its a list of pages just fine without a title. It would also be useful if the My Pages pane could be resized while open. It's possible to manipulate tokens on the map while it is, and that can be useful when moving people to a new map, but you have to be able to see the map well to do that, and with a lot of maps in a folder, it takes quite a bit of room.
