Since there are so many suggestions floating around, most of them buried deep inside dozens of different discussions, I think it'd be useful to add a "Suggestions" tab in addition to the ones that are already along the top. The tab would be a dedicated list of suggestions, one to each entry, and users could up/downvote each one and see its status (e.g. "under consideration", "under development", etc). This might reduce a lot of clutter in the discussions section, as well.
Yes! Duolingo needs a dedicated space where users can contribute suggestions.
