I was designing an interface which was a popup showing a document (pdf) and right below its metadata (user who scanned it, doc name, doc-relative metadata, etc).
Since I was tasked to make an Editor for that metadata, I came up with tabs, one was called
Document View, and the other
My boss didn't like it, because he says that it was not good looking, that it was confusing because tabs were "actions", so I ended with a slideUp() of metadata and then slideDown() of the editor on Edit button click.
Can someone tell me if my boss was indeed right and what is the difference with MS Word Ribbons (for example).
