"This seems almost completely useless" - seems pretty harsh. Someone making a cool project, open sourcing it, and documenting it really well is something that should be praised. Of course Google is going to do much better, its a company focused on search.
Are there any plans to support batch upload from other services (like Google drive, Dropbox, etc)? It would be nice to be able to migrate lots of folders and files in one click instead of having to download every file and then upload each file directly to Amium.
