Thanks for the search function, it works great!
Should there be a search tab in the document.php also? It might be confusing as it appears and disappears now.
Another thing: can the file metadata be edited later on? I couldn't find a place for this even as an owner of the files.
Both of these are very good ideas, and I admit they would already be in if there was a little more time available. A little patience and I 'll do these, too.
