Your search doesn't seem to work on file names, which makes it pretty useless. Additionally, since there his no obvious way to display file names, I can't really find it manually either.
Dropbox is much easier to use.
I agree. The search feature is horrible. I literally save a file and then try to search using the name and it doesn't work. Useless and discouraging to use when I could just save my things elsewhere and find them more easily.
