and it now looks fairly all right. The new dialog is certainly different, and I will have to see how I like it, but it certainly makes a big difference now that it expands to use all the space it needs. And your update has it opening the list by default.

)
Incidentally, this also gets rid of the Case of the Incredible Moving Window.
