I would like is an acceptable definition in the drop down box (although it is "vorrei" really) but it didn't take it as correct. I did report.
"Vorrei" (Present conditional) is a more polite form but it shouldn't be accepted here since there is a clear difference between "Voglio = "I want" and Vorrei = "I would like".
Yes, I realize the difference--but one would think they would not give "vorrei" as an option in the drop down definition list. This happens to be one I know the difference in, but I suspect they do it for other words, too. I just don't know enough to know! yet. haha :-))
Sorry for misunderstanding your point. Yeah, sometimes there are mistakes in dictionary hints, but whenever you spot one just report it (I usually specify the word/s in the text field for "other problem" as well).
