In the document tap I can see an icon that allows me to "fold in" all folders.
It would be very helpful if there is another one that allows me to "fold out" everything at once.
That gives me the opportunity to see the whole structure and all the files in that project.

My particular problem:
The folder structure, in the project I’m working in, is quite complex and opening every subfolder in the browser via Internet takes a long time to get an overview about the whole structure. I have a file that I’m not quite sure, where to place it in and want to see, if there is folder for it already.
