I always wondered why nobody else seemed to follow the lead of Lotus 1-2-3 for Windows. Use "save" and "load" icons that portray arrows pointing to and from folders [1]. Never have to worry about a floppy again.

Turns out, these guys just did that. Except with documents [2] and clouds [3] instead of folders. Guess iOS did away with those.
