I agree that looks a bit more pleasing and less confusing, but I'm not sure that the function of the + sign is obvious enough. I know that a plus "adds" something or sometimes "reveals" something. I suppose with my background knowledge of Pleco, I also know that I (probably) can't add a new entry from this screen, I can't add a note (since Pleco doesn't support that), and I can't add a bookmark (because Pleco doesn't have that either), so it must be a Flashcard. But I need that background knowledge, and I need to go through that process of elimination in order to decipher the meaning of the plus sign here.
I also really *do* like to pick the dictionary when creating a card (although perhaps that will be less relevant soon, depending on how definitions/examples are shown in flashcards), so I'd be a bit disappointed if that functionality goes away or gets put into a 2nd step (although I'd live with it if it's the most elegant way, given all of the trade-offs).
What about something like one of these?:
1) Gets the + away from the dictionary name; and uses the full dictionary name instead of a potentially confusing abbreviation.
2) Text makes the purpose of the + more obvious: it says "Flash Add" now. More meaningful, but at the expense of extra clutter.
3) Use some sort of iconography to show that the "+" relates to a flashcard, at the expense (perhaps) of a "cleaner" look.
