Is there any way to have the translation boxes automatically show up? I don't like having to hover over them in order for them to show up.

As far as I know, No way to do that exists, unfortunately.　Well having said that I've thought about it too, and I actually want that feature, though.

Throw this in your custom CSS, then mouse over the notes that appear and they'll move into the correct position.
div#note-container div.note-body { display: block !important; }
