My specific need came from using a plaintext editor (Plaintext, although the issue is similar in IA Writer, Byword, etc.) where I can create new folders to organize my .txt docs, and I create new docs in them, but I can't move existing ones into or out of folders.
So I thought, surely I can switch over to the Dropbox app, move the files to the desired folders there, then come back, but that's not the case. There's not even a move function in the Dropbox app.
Is there some way on an iPad to move a file in Dropbox to a different folder in Dropbox (that doesn't involve logmein or some other VPN app that lets me access my Mac)?
