When can we expect "Organize Library Files in Folders (Beta)" to go GA? We aren't on Lightning yet, but while testing in a sandbox, I can see we can add folders/sub-folders to libraries in Lightning. However, we cannot add files to those folders yet and have to bounce between Classic and Lightning to accomplish a simple task.

When can we expect this sub-folder functionality in Classic? I know I can view the sub-folders via the Files section (not within Libraries) but I cannot add files to sub-folders.

And lastly, when can we see sub-folders in Salesforce1? I can see the Library and the files within the library that are contained within sub-folders, but cannot see the folder structure yet.

It's great that these things can be done via API, but that isn't very helpful to those of us that aren't familiar with code. Is there a set of instructions available that can be followed to bring the folders/sub-folders and content in without having to jump through so many UI hoops?
