Save the current folder expand/collapse status of queries with the pbix file.

[Quorthon1965]

It's driving me mad that every time I work in the Power Query editor all the folders and subfolders are automatically expanded to their fullest extent. This wastes my time as I have to fold them away again in order to concentrate on the task at hand. Please can you make the editor window open with the folder tree in the same state as it was when I last opened it. Thank you.
